Q: Adjusting the width of the matrix

srijanI am typing a matrix in a document class but its size is too large to fit on the width the page. I have also used tex code \tiny but it is making font of matrix entries too small. I am not able to fix this problem. Could anybody help me? I would be very much thankful to you. Here is the tex code...

The OP has loaded a package often! And, no \makeatother...
And, there I go saying "you have missed commas and semicolons" while the whole thing is a big blasphemy.
 
9:32 AM
@kan I like \oddsidemargin=0.01in: less than 3/10 of a millimeter. They are quite fussy on measurements, it seems.
 
kan
@egreg So, you mean, the OP's way of doing it is OK?
 
@kan Of course not! Look at the definition of \singlespacing! It's incredible!
 
@egreg hadn't heard of \selectfont I assume.
 
kan
@egreg Yup! I did not see that!!
 
@DavidCarlisle \tiny\CS!
@DavidCarlisle What about \linespread{1}\selectfont?
 
9:38 AM
@egreg At least it has the benefit that it works unlike all the instances of {\centerig hello} that get posted that don't work:-)
@egreg what about not messing with the baselineskip at all?
 
@DavidCarlisle You know that some institutions still insist on double spacing. By the way, also subfigure is obsolete.
My opinion is known: double space is only a way to artificially blow up the thing.
 
@egreg Yes I know but it seems modern students take a lot more notice of rules than we used to:-) When thesis was submitted on paper, bound, the university authorities I knew may tut a bit if it wasn't exactly the correct format but they'd never reject a thesis or fail you because you'd proved the theorem of the century but used the wrong linespacing.
 
@DavidCarlisle We had basically no rule. :)

Q: Similar to Excel's line charts?

giannisHow could I create charts as the follow ones, which were produced by Microsoft Excel?

Looks like the 'which package for plots' question, which of course I can't find. Anyone?
 
@JosephWright Maybe this

Q: How to draw graphs

RahmanMaybe this question should not be here, but for me it seems the only way to get the answer! My questions are: Which program a mathematician can use to write a paper in mathematics which contains a lot of geometrical graphs? How they drew the pictures in the books? Is it just hand drawing and...

aaah not that kind of graphs
 
@percusse We tend to stick to the metamathematical meaning, so 'graph' is not what I'm after: definitely 'plot'
 
@PauloCereda That's the soundtrack for COPS. Where US police beat up homeless people.
It's entertainment, apparently.

@NicolaTalbot Stefan Pinnow has contacted me about dickimaw-books.com/cgi-bin/…: he's keen to get a solution :-)
 
@JosephWright I was just thinking it was about time to sort out the bugs in glossaries ;-)
In addition to the bugs, it seems I've documented something I never got around to implementing!
@JosephWright I think it may be related to:

@tohecz: I got myself a Yamaha. :)
 
@PauloCereda Oh my good! :D
 
@tohecz No money for a Clavinova, but got me an Arius YDP 161. :)
 
@PauloCereda not a bad choice :)
 
@tohecz Prices are very expensive here. A good Clavinova is twice the price. :(
Now, I need to wait 15 days until it arrives. :)
 
@PauloCereda oh I know. I've just ordered something from the U.S., and I've paid 21% VAT more :( I would pay extra 12% import taxes if it were over EUR150
Damn taxes ...
Well, now I gotta go, we have the evening service at 6 and I play the organ there :)
 
3:36 PM
@tohecz How nice! :) Have a nice evening, Tom! :)
 
3:55 PM
@PauloCereda Nice. I wish I could play the piano :)
 
@cgnieder Speaking of which, I saw a guitar in a post of yours on G+. Is it yours?
 
@PauloCereda Yes :) The bass guitar plays and sounds nice. The semi-acoustic guitar only looks nice, though :)
 
@cgnieder Wow! Awesome!
Let me +1! :)
@cgnieder: I love the bridge in your guitar. :)
Very classy!
 
@PauloCereda making music is even more fun than TeXing :)

@cgnieder How about making music with TeX? :)
 
4:02 PM
@PauloCereda unfortunatly the jazz-guitar looks better than it sounds :( I probably need to exchange the pickups
 
@cgnieder: I have an old guitar here, I was planning to put a sticker enclosing the neck: \begin{guitar} ... \end{guitar}. :)
3
 
@PauloCereda problaby the most fun ever!
@PauloCereda :D
 
@cgnieder Is it only one pickup or a double-one?
 
@PauloCereda one of them is kind of ok but I think I would exchange both of them. Not sure if it is worth it though: it sounds awful un-amplified, too - well I got for free so I don't want to complain :)
 
@cgnieder Oh. :)
@cgnieder: I have a few string instruments, but I only know the basics. I once posted this picture to Frank (which is a bass player, if I recall correctly): i.stack.imgur.com/8l97V.jpg
 
4:09 PM
@PauloCereda I count five! That's nearly as many as I have! Minus the ones that sound awful that's one more than I have :)
 
@cgnieder :)
Now I need to learn how to play them properly. :)
 
@PauloCereda I know that kind of problem. Every other day I decide to practice more but it's like a new year's resolution... never made true
 
@cgnieder :)
@cgnieder: Trivia: @David can play any instrument using \tracingall. :)
 
@PauloCereda Or M-x play-guitar
 
@egreg ooh that one too. :)
 
4:25 PM
@PauloCereda @egreg :)
 
4:38 PM
Ooh, I think I've finally fixed all my glossary bugs :-)
 
@NicolaTalbot Very dangerous thing to say. @DavidCarlisle thought the same 20 years ago when he wrote longtable. ;-)
 
@egreg Okay, change that to "I've finally fixed all the bugs that have been reported on my bug tracker" ;-)
 
@egreg LOL
 
@PauloCereda what was so funny?
 
@DavidCarlisle I remembered a joke. :)
If you want more effective programmers, you will discover that they should not waste their time debugging, they should not introduce the bugs to start with.
                       --- Djikstra
@David: we could invite @egreg to test buttercup. :)
 
4:54 PM
@PauloCereda that's definitely bug free.
 
@DavidCarlisle Indeed. :) So far, no bugs found. :)
!!/eightball is our code bug free?
@PauloCereda Psmith, the TeX bot: The great 8-ball says: signs point to yes.
!!/eightball Do I need to fix bugs?
@PauloCereda Psmith, the TeX bot: The great 8-ball says: too busy looking for bugs in longtable.
Oopsie.
 
5:11 PM
@Paulo @cgn You have so many? I have only one but it is enough for the scout campfires or evening in a tee-pee :)
 
@tohecz I have seven instruments, four of which are actually good. They all serve different purposes... if I only had the money I'd have many more... ;)
 
@cgnieder I'm happy with my guitar. If I had the time for it, I would buy a 5-string banjo, but it takes damn lots of time to learn it, and I know I don't have that much time, given my primary interest is piano and organ.
 
Has anybody else problems uploading an image to imgur on TeX.sx?
 
@PauloCereda What is the 10-string thingy in front?
 
@tohecz It's a typical Brazilian instrument, it's called viola caipira. :)
 
5:21 PM
@PauloCereda and it is a 10-string aka 12-string guitar?
 
@tohecz It's a 10-string instrument with a different tunning than a "normal" guitar.
 
@tohecz Oh yes, a banjo would be cool...
 
@PauloCereda ok kool
@cgnieder we have some good Czech banjo players and I always drool when I hear them
 
@tohecz: a nice song in action with a viola and guitar: youtube.com/watch?v=3S_RdLhJGtI (that guy is the one that autographed my viola, I played with him, but in piano + viola). :)
 
@Paulo I so damn love the octave sounds :)
 
5:25 PM
@tohecz unfortunately I don't know any Czech music :(
 
It is as welll something I love about organ
 
@tohecz harmonics FTW. :)
 
@PauloCereda how is it tuned?
 
@cgnieder Every region has its own tunning, and there's also the personal taste of every player. :) There's a story that people used to "duel" by playing/singing, then they changed the tune every time in order to avoid the other player to copy the notes. :)
My tunning is: E, B, G#, E, B
 
@PauloCereda harmonic tuning, like a banjo :)
 
5:29 PM
@tohecz, @cgnieder: some sort of blues played in the viola, by our greatest player Almir Sater. :) youtube.com/watch?v=4SRHpRcpZD8
@tohecz Yep! :)
 
@PauloCereda Ah, so there is no standard tuning?
 
@cgnieder No. :) That's the beauty of the instrument. :)
 
@PauloCereda kool
 
@PauloCereda slide guitar players use similar open tunings - it's fun to play with different tunings but always a challenge
 
@cgnieder slide guitar - is it the thing that I know as "dobro" ?
 
5:37 PM
@cgnieder Indeed. :)
 
That was a bit annoying. We just had a power cut. My computer didn't like that.
 
@tohecz not exactly... a dobro is a kind of resonance guitar that is often played by slide guitar players. Slide essentially means you use a bottle-neck for playing. Sonny Landreth would come to mind...
 
@cgnieder David Gilmour on High Hopes. :)
 
@tohecz a lap steel guitar is also usually played with a slide
@PauloCereda haven't heard that one in quite a while... :)

7:54 PM
whats wrong with:
\let\oldstctr\stepcounter
\newcommand{setfirstandstep}[3][1]{%
	\renewcommand\stepcounter[1]{%
		\ifstrequal{##1}{#3}{%
			\ifnumequal{\value{##1}}{0}{%
				\setcounter{##1}{#1}%
			}{%
				\addtocounter{##1}{#2}%
			}%
		}{%
			\oldstctr{##1}%
		}%
	}%
}
\setfirstandstep[4]{9}{chapter}
loading calc and etoolbox
 
@leo redefining stepcounter is pretty dangerous, what do you want the code to do?
 
leo
@DavidCarlisle I want to \setfirstandstep[4]{9}{chapter} makes the sequence of chapters looks like 4, 9, 13, 21, etc
 
@leo That so the wrong way to do that:-)
 
@leo It would be better to modify \chapter so that it increments the chapter counter using \addtocounter instead of \stepcounter.
 
@leo It would be easier for the counter to have the values 1,2,3,... but make a shower macro like \myarabic that shows them as 4,9,13,21,.... using some math package
 
7:59 PM
@JosephWright Bug fixed and new version uploaded to CTAN :-)
 
@leo what sequence do you mean exactly? I don't see the pattern
 
leo
@NicolaTalbot the thing is that I want this to be usable with various counters
 
@tohecz exactly (there was an answer doing exactly that the other day)
 
@leo Then @tohecz's suggestion is the best way to go about it, I think.
 
leo
@tohecz but there counters that are not showed using \thecounter or \arabic{counter}. Consider the question counter from exsheets package
 
8:01 PM
@leo \renewcommand\thequestion ... would not work?
 
leo
@DavidCarlisle f(n)=4+(n-1)*9
 
I recommend you to make it into a question. Only then you'll formulate your problem in a clear and solvable way ;)
@leo you missed 17 in your example ;)
 
leo
@tohecz already tested, and not :-). Lets ask to @cgnieder why?
 
@leo was it you that asked the question the other day (I just failed to find it) but just use \renewcommand\thechapter{\the\numexpr4+(\value{chapter}-1)*9\relax}
 
leo
@tohecz good idea. I would like to have counters to step as f(n) does but with f(n) any integer valued function. I was thinking in do something with pgf but it seems redefine \stepcounter is not the way to go
 
8:05 PM
@tohecz that's what threw me:-)
@leo You don't need pgf for a linear function.
 
leo
@DavidCarlisle thanks. But the problem is that there are counters which are not shewed using \thecounter or \arabic{counter} or the others. As I have said, I have tried with the question counter from exsheets package. Redefining \thequestion don't do what I want.
@DavidCarlisle true, but I thinking in general. It would be nice to do that with any function
of course not any, but you get the idea :-)
I'll ask a question
 
@leo more commonly there are counters not incremented with stepcounter (they may be set with setcounter or incremented with the \advance primitive, you can't catch everything, if you redefine \thexxx then at least you catch the cases that are doing it right.
 
leo
@DavidCarlisle I see. By the way I've hear you like Tikz :-) have you seen this
 
@leo I should show that in picture mode

Q: Stereographic Projections

leoTake the unit sphere in the three dimensional space. A plane through the half of the sphere perpendicular to the vertical axis. Pick a point in the plane and draw the line which joins it with the north pole of the sphere. The intersection of this line with the sphere is the stereographic image o...

 
8:20 PM
@leo No, that is not what you want. What you want is having the counters used in the exsheets package to be shown that way.
 
leo
@tohecz why restrict to those counters only? It will be fun to solve it for any counter once and for all
it could be a funny package
 
@leo funny but probably very fragile, IMHO to fragile to be usable :-/
 
leo
@tohecz what do you mean by fragile in this context?
 
@leo that many other packages could get broken, like calc, zref, ...
 
@leo How can you solve it once and for all. It is already the case that counter printing functions can be any expandable function of the underlying register, that's how you get \Alph or \Roman etc, using \numexpr is just a natural extension of that. But whatever method you use of specifying your series if you also allow people to set and extract the value of the counter using arbitrary tex primitives then it will fail.
 
leo
8:26 PM
@tohecz perhaps that can be avoided. I agree with you that the right way to do this is to have a nice counter printing command. That's what I'll ask
 
M-x burger
@DavidCarlisle: @egreg is watching the game, quick go harvest some rep. :)
 
@PauloCereda Herbert is well ahead of us anyway
 
@DavidCarlisle Oh! :)
PSTricks vs. picture mode. That will be interesting. :)
 
leo
@DavidCarlisle This is pointless. In almost all the case it's enough to redefine \thexxx as you said
 
@leo In the new order we'll remove all the tex primitives and everyone will have to code to the proper interfaces and the world will be a happier place.
 
8:38 PM
@leo you have troubles with exsheets' question numbering?
 
btw, have I told you how genuine makebst is?
 
leo
@cgnieder A bit yes. The thing is that the assigned questions of my homework are those with number 4+(n-1)*9. So I want the questions to be numbered properly. I've tried \renewcommand\thequestion{\the\numexpr4+(\value{question}-1)*9\relax} as Davide suggested. But it doesn't work. Then I did it:
\let\oldstctr\stepcounter
\renewcommand{\stepcounter}[1]{%
	\ifstrequal{#1}{question}{%
		\ifnumequal{\value{question}}{0}{%
			\setcounter{question}{4}%
		}{%
			\addtocounter{question}{9}%
		}
	}{%
		\oldstctr{#1}%
	}%
}
which works but is not wise as they have just explained
 
@tohecz How genuine is it?
 
@NicolaTalbot I needed to make a small change in the bibtex style. So I opened the .dbj file, removed one % and voilà!
 
@tohecz :-)
I think maybe I should've made my comment an answer.
Is there a neat clever way of converting comments to answers, or do you just rewrite it as an answer?
 
8:53 PM
@NicolaTalbot just copy/rewrite (or get yourself voted to take over from Joseph and gain super human powers)
 
@DavidCarlisle :-) okay, thanks.
 
@leo Hmm, not something I did foresee... Here's a way I would prefer:
\documentclass{article}

\usepackage{exsheets}
\ExplSyntaxOn
\cs_new:Npn \myquestionnumber #1
  { \int_eval:n { 4 + (#1 - 1) * 9 } }
\ExplSyntaxOff

\NewPatternFormat{x}{\myquestionnumber}
\SetupExSheets{counter-format = qu[x]}

\usepackage{lipsum}
\begin{document}

\begin{question}
 \lipsum[1]
\end{question}

\begin{question}
 \lipsum[1]
\end{question}

\begin{question}
 \lipsum[1]
\end{question}

\end{document}
 
Can someone tell me if there is any redundancy here?
 
leo
@cgnieder I see. Thanks :-)
 
I mean Microsoft.... come on.... for once
 
8:56 PM
@cgnieder which is essentially the L3 version of what tohecz and I suggested (keeping the register incrementing by 1 and adding the function to the toplevel print command)
 
@DavidCarlisle quite :)
 
@percusse well it depends if you just want to run stuff or if you need to know whether it runs with the various versions
@cgnieder Yes the comment was for @leo really:-)
 
@DavidCarlisle I feel that whichever I remove will break something immediately.
 
@percusse That's normal. it's Windows.
 
@DavidCarlisle But I want to install some compilers for matlab mex builds and I also know; that will break one of these...
Best is to change profession it seems :)

@PauloCereda It was the Manoa.

@cgnieder not seen any this year:-) I thought Psmith may have some info, but he let me down as usual.
 
@NicolaTalbot ooh!
 
@PauloCereda My mum's cousin told me about it, but google is being unhelpful and thinks I mean the place.
 
@NicolaTalbot Ah I'll investigate too.
 
@PauloCereda Thanks :-) He was with the royal mail shipping company, so I expect it would've been RMS Manoa.
