Hi Maple experts,
I have a seemingly simple procedure that is supposed to create random matrices.
What surprises me is the fact that it takes more CPU time evertime I call it (even in a fresh session). The procedure is as follows:
```
Feynman_random_rho := proc(N::posint, d::posint:=2)::'Matrix'(complex[8]);
#
# returns a random N-qudit density matrix where the optional second argument, d,
# specifies the dimension of each subsystem. By default, d=2 is assumed so that
# an N-qubit density matrix is generated.
# The density matrices are uniformly distributed according to the Hilbert-Schmidt
```

Hello,
I'm trying to integrate (for a homework) the Planck radiation formula. But the result (see the Maple10 worksheet below) is so strange (polylog(4,exp...) stuff) that I can't figure out what it means. I tried to compute taylor series at T=0 (because the exercise is to prove that integral is proportional to

`T^4`

) but Maple can't do it.

If i have this matrix in maple, what does it mean the last row (0 0 0 0 1)
and what is 1? Is it like 2a+5b-6c+2d+6e=1.

Hi!
I am trying to write a question involving a second order initial value problem. The 2 conditions are
u(0) = $a
du
--(0) = $b
dx
but I am not able to code it correctly. I have tried
...
$eq2=$mathml("(d^2u)/(dx^2)+($mamb)(du)/(dx)+($ab)u=0");
$eq3=maple("printf(MathML:-ExportPresentation(u(0)=$a))");
$eq4=maple("printf(MathML:-ExportPresentation(du/dx(0)=$b))");
...
This works fine for the first condition, but I get
du
---- =
dx(0)
for the second one. Is there a way to get the "(0)" in the right place, either using "$mathml" or "printf"?
Thanks in advance for your help.

So I put in my first line and hit return. Maple spits out the second in which my 47.3 lbs/ft^3 gets turned into SI units while the other two quantities are left in FPS.
Can someone tell me why?

Is there a way in Maple to compute the symbolic upper bound and lower bound of a given symbolic formula?
Thanks.

I have no idea what LaTeX, is other than a helpful tool for publishing.
However, I'd like to start using it for several reasons, but don't know where to begin.
Can anyone suggest a very first starting point for someone in my position ?
v/r,
Thanks,

I'm new to Maple. I'm quite competent with Matlab, with competent meaning I have some experience using it for analysis of physical data. I'm very experienced in using my TI-89 Titanium
I have decided to give Maple a try since I'm not satisfied with the way Matlab handles symbolic expressions. I also want to tryif there's anything better than Matlab.
I'm majoring in physics, and I hope to get my bachelor degree in a year. So far I have been writing all my assignments that needed a computer in Microsoft Word, but that is far from satisfactory. I have been considering learning myself LaTeX, but I have been thinking if it's just as good to use Maple to write articles and documents. Can I write an article as fast in Maple as I can in LaTeX? Speed is key for me naturally. Can I write LaTeX directly in Maple?

I am writing a program in which, after some calculations, I want to give the user some information and then ask them if they want the program to continue. I've tried using readline(terminal) and readstat, but I have the following problem: the information that I want the user to see is printed at the bottom of the screen and Maple gives a dialog box to get the user input. With the dialog box showing, the user can't scroll down to see the data. Is there a way to make sure that the data shows up before the dialog box pops up? Or is there another way to get input from a user?

I was wondering if I could change the values on the x-axes. I want to have the value 3500 at origo and 0 at "3500" normally is, can this be done?

On subscripts. I like to use them as part of variable names but Maple does this to me.

Lets say I have

My question is about how Maple handles differentials.

In its derivation of an equation for pressure as a function of depth my physics text comes up with this:

from which it gets

How can I write with 2D math in text mode? That is, I want to create a document with mathematical expressions but I don't want Maple to do any mathematical operations on them. Imagine that you're trying to write a page in a textbook with expressions put in normal notation and interspersed with comments - that's what I'm trying to do.
I've tried Text>Maple Input, Text>2D Input, Text>2D Math, Text>Normal, etc, etc but they all just put out 1D. And if I try to use "Math" instead it invariably does some sort of simplification or normalization or some such when I don't want it to touch the expressions I enter at all.

Hi,
I have a question. I work with maple in a fairly unusual
way. I use the vim editor and the command line interface (don't try to change this it won't help).
Then I typeset my results using the latex mode.
I am wondering of late if I can read my input into the
graphical version of maple and control the formatted output
produced by the gui. i.e. is there some analog of
`latex/special_names`[x1] := `x_1`
For the gui interface. I can't seem to find this documented anywhere.
Thank you,
Derek

Hi all
I have a(x) and b(x), a(x) is only interesting from x=0..5 and b(x) from 5..10. How can I define those to into one c(x)?
I guess I need the piecewise function, but I don't understand anything from the help file.. Can anyone please explain it to me, thanks.
