@Nasser Take a look at the answers posted by user21: mathematica.stackexchange.com/users/18437/user21
The majority of them involve finite elements or related material.
 
@MarkMcClure thanks, had a quick look. Yes, I see. I am trying to decide now if I should take FEM course or linear systems, so was wondering about how M FEM is used.
 
Well, I think the FEM implementation is awesome!
 
but if I take the FEM course, we'll be coding things in Fortran :( (this is what the teacher code is in) but will use M to at least verify my solution. But have not yet decided yet. I like linear systems and control also.
 
There are a few bugs and limitations and I think that some gui tools to input regions would be nice, especially for beginners, but overall, it's a great tool.
Obviously, I can't advise on FEM vs linear systems.
Good luck though!
 
@MarkMcClure thanks. Yes, all the examples of FEM looks really nice. I think it is easier to use compare to Matlab's FEM toolbox/functions, which I tried and did not like at all.

I actually do like Matlab's PDE toolbox. I'm an intermediate user of Matlab at best and found the GUI to be quite useful. Ultimately, though, the power of the programmatic approach is much more powerful, which is why I think the V10 stuff is such a welcome addition.
Of course, they're both more pleasant than Fortran, I imagine. :)
 
@MarkMcClure I only used the GUI part of the pde toolbox. Matlab does not have, as far as I know, the regions functions added in V10, very useful. Yes. Fortran is not too easy to use once one is used to M. had to write numbers to a file then load them using M or matlab just to plot something.
I think for control systems, Matlab has more functions and features over M. I was hoping they'll add more stuff to control systems in v10, but only 2-3 functions added, that is all.
@MarkMcClure The reason I think M can have an advantage over Matlab in control (more easily than with numerical) is that one can take advantage of symbolic computation much more with control and dynamics, which M is better at.
 
Right - I don't know control systems at all but I definitely agree that any numerical scheme that benefits from some sort of symbolic pre-processing is exactly where Mathematica might have an advantage over Matlab.
You see this in numerical integration a lot.
 
@MarkMcClure someone should tell Wolfram to hire more control engineer programmers to add more functions to that area. This is an opportunity for WRI to take more advantage of its symbolic powers. There is a book on this subject actually, here it is amazon.ca/Symbolic-Methods-Control-System-Analysis/dp/toc/…
 
@Nasser Take the control systems class and apply!
 
@MarkMcClure if I get an A, may be :)
 
2:19 AM
OK, well "may be" is spelled "maybe" - so maybe your teacher grades on that, I don't know. :)
Sorry - couldn't resist. Every teacher has their quicks and I'd just hate for you to not get your A for something silly.

Is it just my imagination, or has the Internet September started on mma.se?
That is, hordes of clueless questions as semester starts...

Hi, a question question,How to scan a function with multiple slots?
For example, `f` on `{1,2,3,4,5,6}`
gives
`{f[1,2],f[2,3],f[3,4],f[4,5],f[5,6]}`?
Thanks

@xslittlegrass one of these:
f@@@Partition[Range[6], 2, 1]
Developer`PartitionMap[Apply@f, Range[6], 2, 1]
