My previous blog entry was a real success. Even though my original idea about multi-part MIME has not gotten anywhere, I do now have a concise way to package a maplet with supplemental files in a single package that can be downloaded via the WWW and automatically extracted and executed. Most of the ideas were presented by acer. acer first suggested that I look at the interactive interface to the InstallerBuilder. The idea here was to embed the maplet in a worksheet saved in a help database (hdb). This did work, but was not suitable for actual use due to the overhead of the installer. In the attempt to reduce this overhead, acer then supplied some code that used march and LibraryTools. To test the product of this interaction, download the file at the URL http://www.math.sc.edu/~meade/TEST/SimpleTest.mla.

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. View 6573_problem.mw on MapleNet or

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. Bo

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?

Note added: As correctly pointed out by Joe Riel in his post below, my function fromTree fails doing what it is supposed to do for expressions which contain lists and/or sets. For a version of fromTree which behaves properly (I believe) also for expressions containing lists and/or sets, see my post below. Consider the following two functions:

toTree   := x -> `if`(op(x) = x,x,[op(0,x),map(toTree,[op(x)])[]]):

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.

Hello! So glad to become a part of this community, I am loving Maple. So here is my question: I know c++ fairly well (need to freshen up) and the same idea with Java, Ive seen I can incorporate languages into Maple, or so it seems. What type of things am I capable of doing? And along those lines, any suggestions to what path to take in order to learn such powerful tools? I am currently working on a bachelor/masters in engineering and would love to know Maple better then I do my own Fiance (just dont tell her). Thanks in advance!
