How long is MaplePrimes going to remain in beta ? Are there more features planned, or are you just waiting for a more appropriate time to make an announcement ? Personally, I think it's done, and overall it's a very good job. By the way, I hope the company makes a good effort to promote this site at the conference. Set up a computer set up in the main lobby where people could see the site. Just use a notebook with external keyboard, monitor, and mouse, and mooch wireless internet from the venue. On a sidenote, I think wireless internet was probably the most requested feature of last year's conference.

I've had considerable difficulty in integrating products of trig functions with Maple. It usually expands the trig functions into forms that just are a mess to deal with. So, I usually handle this by splitting an expression into two parts: a constant term that doesn't depend upon the integration variable and a dependent term. In the past, I've usually done this by hand but have now created a procedure to do this automatically.

Hello, I have tried to run the Maple 10 program on my Toshiba Tecra M4 TabletPC and it runs fine until I go to Tablet Mode. The only part of the program that will run in Tablet mode is the Classic Worksheet. The symptoms are that the windows that appear in say the documentation mode (in Tablet Mode) come up but are solid gray. The program seems to hang. Now what I mean by "Tablet Mode" is that you flip the touchscreen around and lock it on top of the keyboard. This cause the display to go from a horizontal presentation to a vertical sheet of paper presentation. Regards, Dave

FYI, there are MathML character entity errors in Maple 10. This causes problems when copying MathML output from Maple into other programs that expect valid MathML. I only checked the Greek character entities, as that's where I was running into bugs. The incorrect entities as output by the Maple MathML[ExportPresentation] command and the corresponding correct MathML entities from http://www.w3.org/TR/REC-MathML/chap6/byalpha.html are (lower and upper case Greek characters only):

Most of us are very passionate about Maple. This is not something that I'm accustomed to stating in public but in the spirit of Valentine's day, I thought it would be appropriate. Also to mark the occasion, I created a new poll to see just how deep the roots run in this community. Feel free to disclose sordid details of your first time by including a comment :-) T4.

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.

MAPLE does not have the capability of plotting nice (say, round) FILLED IN points, and "hollow" points are very often hard to distinguish in a window cluttered with graphs. I pointed this out to the Maple Support Team, and the following roundabout was suggested: > with(plottools): > c := disk([9,1.5], .2, color=black): > > d := disk([2,2.8], .2, color=black): > > display([c,d],scaling=constrained,view=[-10..10,-10..10]); > display(p1, p2, p3, p4, p5, p6,c, d, scaling=constrained,view=[-1..10,0..10]); > display(p1, p2, p3, p4, p5, p6,c, d,view=[-1..10,0..4]); However, the BIG inconvenient of this roundabout is that in reality it plots little circles. So, if the scales in both axes is strongly different (think of plotting monthly salaries, in dollars, against time, in months) you don't get round points, but very flat ellipses.

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.
