I'm working with lengthy computations in Maple right now and I was just wondering whether it it possible to display some kind of "progress bar" after you hit the return button to start the computation.

At least in the form that text is displayed (e.g. "now is a good time to drink your coffee, computation may take a while") BUT that vanishes after the computation is complete.

Hi there,

I try to plot several graphics and print them out as follows:

for i from 1 to n do
  p:=polygonplot(...):
  disply(p);
end for:

but nothing is being diplayed. Doing that just once does the job but I need those plots for large n...

Long story short, running a loop that takes random variables and does various statistical things to them.

The loop has to run about 10^7 times with the final value going into an Array but I cant do that because the Statistical stuff such as CumulativeDistributionFunction takes up so much memory that I end up losing the kernel.

But... Today I came across the gc() command. I put this in at the end of my loop (before the end do), and lo and behold I was using virtually zero memory for the loop. Only what was needed to fill an Array.

So Maple and I are not the greatest friends and I need help. I have searched google, this forum and other forums for help to no avail. If somebody would be so kind as to help me with the problems that I am having that would be greatly appreciated.

I think the problems are in the initial and boundary conditions because there are so many recursive statements but I am unsure how to enter these so that I get a favourable result. Without the boundary and initial conditions I do get a general solution.

I would like to use a series of Maple worksheets, written by Professors Malidi Ahamadi and Jean-Jacques Gervais, designed to compute the normal forms of ODEs and PDEs. The code was written for an earlier version of Maple (maybe version 7 or 8) and doesn't run anymore on Maple 13. I would like to make the necessary adaptations to the code to run it on Maple 13. Unfortunately, I am no Maple expert...

When I run the worksheet, the following error message shows:

Any reason why the show Numb3rs mostly uses Wolframs Mathematica?  Being a Maple fan I'm a tad bit dissapointed. 

There's a whole mathematica website devoted to the show Numb3rs http://www.numb3rs.wolfram.com it's fairly good and still under developement.  Any plans for maple to so something similar?

I installed Maple 13 and Maplesim 2.0 in a brand new computer I ran the robot simulation successfully but as soon as I ran windows updates and the rest of applications it not longer  work. it just gives me a blank windows with the tool bars.

Does anyone encounter this problem? How do you solved it.

I updated my video card with the latest drivers; and follow the instructions in  regards to installing the latest Java

I am trying to do the following sum

with(numtheory):
sum(bigomega(j),j=1..n)

But I get this error message

"Error, invalid input: numtheory:-bigomega expects its 1st argument, x, to be of type integer, but received j."

I have tried

assume(j,'integer');

but this has no effect. I'm a bit puzzled why Bigomega doesn't work in summations as  other Numtheory functions I've used have all worked.

Maple 13 help describes at least two ways to invoke classic maple, one, for example, through the Windows start - all programs -> Maple 13 .  But there sure is no classic Maple option there.  Where is Classic Maple?  ..........Edgar

Hello,

suppose I have two (or more) different matrices, not necessarily with the same number of rows but with the same number of columns.

I know I can use RowSpace in the LinearAlgebra package to obtain the RowSpace of one matrix, but I would like to consider the intersection. Is that possible?

(In fact, I am particularly interested in the vectors in that intersection that only take the values zero and one, or in other words: all non-zero entries of which are equal. Would there be a trick for that?)

Many thanks!

Please help me to Solve the following problem?

3^2^3*3^2^2=?
