I'm trying to share data on wolframcloud, first CloudPut[Compress@data, "mydata", Permissions -> "Public"], and then CloudGet["mydata"]. In order to make sure it works, after I CloudPut the data, I sign out wolfram cloud in Mathematica. But when ClouldGet, it asks for login. Is it always required to login if we want to use CloudGet even for accessing public data?
I want to share some notebooks to my advisors and they don't know their wolfram accounts.
@Sektor It wasn't actually much of an answer as the question was very basic and rightfully closed, but I don't see why that warrants a downvote. Let's see whether I get more. Thanks again!
@Szabolcs using `ConfigureMaTeX[ "pdfLaTeX" -> "C:\\Program Files (x86)\\MiKTeX 2.9\\miktex\\bin\\xelatex.exe"]`, I get output as expected (i.e. MaTeX["x"] renders just fine.
I want to input a set of divisors of an integer n and return all subsets of these divisors {d_1,d_2,...d_k=n} such that d_1 divides d_2; and d_2 divides d_3; and ...d_(k-1) divides d_k. I would like to have a code that could be understood by a beginning Mathematica user.
@Szabolcs Was using texlive with xetex for years on windows. I think they work perfect and much better than miktex. The only problem I saw is the veeery long time it took for establishing CJK font cache.
But now I don't have any latex locally. I don't use them a lot now, and the free online editors are sufficient for me.
Ok, I think I've found the source of the ticking: I was supplying Fourier[] with a list of pairs of the form {t,x}, but it apparently only takes a list of single values... is there a good way to make it take my values instead besides just scaling them?
Here's what I want to do, initially at least: I have an oscillator, it's in some force field, I've integrated it using the Euler method, so I have a list of points of the form {t,x}, where t is the time and x is its position. Here it is, plotted:
Now (before I do more complicated stuff), I wan...
Rephrasing my problem: I have this {arclength} =
NDSolve[{y[t] == sp[t], s'[t] == Sqrt[y'[t].y'[t]], x'[t] == 1,
y[0] == sp[0], x[0] == 0, s[0] == 0}, s, {t, 0, 41}]. Now have table of "sp" so I want to have table to "arclength". I tried to do this : {arclength} =
Table[NDSolve[{y[t] == sp[[i]][t], s[i]'[t] == Sqrt[y'[t].y'[t]],
x'[t] == 1, y[0] == sp[[i]][0], x[0] == 0, s[i][0] == 0},
s[i], {t, 0, lt[[i]]}], {i, 10}] . But it's not working. How can I do that?
