MaplePrimes Commons General Technical Discussions

The primary forum for technical discussions.
Hello, I am trying to compute an integral, int(1/3*(-6*u2^2+u2*(3*z+9*u3)+z^2-5*z*u3-2*u3^2)*(z-u3)*(z-u2)/(u2-u3)^4, u3 = z .. 1); Warning, unable to determine if u2 is between z and 1; try to use assumptions or set _EnvAllSolutions to true O.K., I try with assumptions: int(1/3*(-6*u2^2+u2*(3*z+9*u3)+z^2-5*z*u3-2*u3^2)*(z-u3)*(z-u2)/(u2-u3)^4, u3 = z .. 1) assuming u2
Just wondering. Has there been any work done on the so-called Chaos Game and other aspects of Wolfram's NKS (New Kind of Science) using Maple? If so, can someone lead me to references to this.
Consider the following equation: base^^(height)=weight where base^^(-1)=0, and base^^(height+1)=base^(base^^(height)) whenever 0.20 <>
I seems that CodeGeneration fortran uses internally lists that can get longer
than 100 elements converting complex procedures.

executing
"Fortran(long_procedure,defaulttype=float,optimize);"

I get the following error message
"Error, (in GetNameReplacementList) assigning to a long list, please use
Arrays"

9.5 handled this without problems.

I join a worksheet that (as very last command) shows the problem.

I reported already this problem to the technical support, but now I post it also here.

We recently installed Maple10 and Matlab 7r13 onto our Gentoo Linux machine. We've gone through the steps outlined in "Configuring a Computer for Matlab" to get the Matlab link working. Both programs work fine on their own and when we load the Matlab package in Maple ( >with(Matlab); ) it displays a list of commands just as it should, but when we try to open a link to Matlab we get the error: Error, (in Initialize) The library matlink.dll/matlink.so cannot be found Does anyone have any idea what to change in Maple or Matlab to point the program towards our matlink.so file? It is located in the $MAPLE/bin.IBM_INTEL_LINUX/ directory.
Occassionally Maple does not make me happy, if I want numerical integrals with more than the 14 digits which are supplied through the NAG librarys - that may be rather slow. So I wrote my own solution using LCC-WIN32 (a (free) compiler system allowing 104 decimal points of precision), where I coded the double exponential integration method. That gives me what I want to have in reasonable time. Details are sketched in the uploaded zip-file (it contains all what is needed to run the stuff). Some draw-back: this is for Windows only and because of OpenMaple at least Maple 9 is need.
Hi to everybody! I am new and I was wondering if someone could explain me what is the +0.*l that appears in matrix of Eigenvalues. In detail, it appears as: Vector[column]([[27250.1116448956418+0.*I], [79.0594032174760884+0.*I], [0.139518868786005380e-1+0.*I]]) Thank you, Katerina

Many Maple users have a preference of user interface, whether it be command line (TTY), Standard (Worksheet or Document mode), or Classic. My personal view is that each may be suited for different types of task. While it's understood that Maplesoft is dedicated to supporting the Standard interface, I understand that some users remain devoted to the Classic interface.

I often use Maple 10 on a 64bit Linux machine, on which the performance of the 64bit Maple 10 kernel is comparatively faster for some types of computation. I discussed this briefly in an earlier post. But there is no officially released 64bit Linux port of the Classic interface. So below I'll mention an unofficial and unsupported way to use the 64bit Linux Maple kernel with the 32bit Linux Maple Classic interface.

I have met several problems trying to install and execute Maple on Fedora Core 4. I begin with Maple 10. Default GUI installation does not work: ============== [root@localhost cdrecorder]# ./installMapleLinuxSU Preparing to install... Extracting the JRE from the installer archive... Unpacking the JRE... Extracting the installation resources from the installer archive... Configuring the installer for this system's environment... awk: cmd. line:6: warning: escape sequence `\.' treated as plain `.' Launching installer... Invocation of this Java Application has caused an InvocationTargetException. This application will now exit. (LAX)
I'm producing some Maple notes for my students, and I'm using the LaTeX "listings" package. This means I can get nice ascii text inside a grey box of the size I want. The trouble is that I also want to include some typeset output, and I'm not quite sure how to mix plain text and mathematics typesetting using listings. Or does somebody know of a better solution? What I want is for the Maple stuff (input and output) to be in grey box, to immediately differentiate it from my other text and discussion. And since the Maple ascii input contains all sorts of characters, the various LaTeX verbatim styles might not be much help.
Hi Firstly, my apologies if my question has been answered elsewhere. I have browsed the forums but couldn't find anything relevant. My problem is this: I'm trying to install maple-10 on a linux machine which is running Linux From Scratch. (What this means is that it's a linux which I compiled myself and so is not one of the supported distributions.) When I run the installation script the Java VM which is distributed with maple is unpacked and seems to be fine. However, my linux was compiled with NPTL and so when the installer checks for the type of threading it decides that the VM and the threading model are incompatible. It therefore sets the variable LD_ASSUME_LINUX=yes and uses this hack to try and get around it. But when this happens the installation program cannot load any shared libraries because this hack breaks the linker.
I am amazed by the behaviour of the following bit of Maple (from maple 10), boiled down from a student project. Looks very buggish to me, but perhaps I am misunderstanding something. I'd be grateful for any comments. (I edited the first line in response to the comment immediately below _ had used ange brackets that were being interpreted as html.) v:=: B:=[0,0]: for i to 2 do v[1]:=i; v[2]:=i; B[i]:=v; end do: B; [Vector(2, {(1) = 2, (2) = 2}), Vector(2, {(1) = 2, (2) = 2})] Added later in the day: as a colleaugue points out, the problem arises presumably because the assignment B[i]:=v leaves B[i] pinting to v rather than the value of v at that time.
I am trying to solve a trascendental equation of the type sin(x)=x, does anybody got an Maple algorithm or have a clue of what metodology can be adopted to solve it. My question goes in two directions: 1) the mathematical way of solving an equation like that 2) the way of implementing the resolution in Maple. For the first topic I knowm this is not the appropriate forum, however since there are a lot of mathematicians particiating I have supposed that someone could help me out, or indicate another forum to post this question. Thank you for your help RV
Is there a way to perform maintenance on Maple 10?

Maple 10 comes in both a 32bit and 64bit version for Linux. It's possible to run both versions, installed to the same base location, on a machine with the appropriate operating system runtime configuration. There are some interesting performance differences between the two versions.

I'll say a few words about the installation. I installed both under /usr/local/maple10 on an Athlon64 3200+ running the x86-64 version of the Fedora Core 2 operating system. I have the 32bit...
