Hi there,

I've created some nice 3D-plots. I want to export them and insert them in LaTex. Exporting to EPS gives me a zero-byte-file but no printable data.

I've already read that I'm not the first to have this issue and there is obviously a work-around by enabling the Classic-Worksheet-mode. Unfortanely this mode appears to be not available in Maple 17 under MAC OSX. 

Is there another way to solve the problem?
Would help me a lot.


Hi there,

I used to work with Maple 15. In Maple 15 the input-font-color was a beautiful plain red. Now I have to work with Maple 17, where the font-color was changed to a way darker red. 

I found a way to change the color in a single worksheet with Format-->Character-->Color. But I want to change it globally and permanently, so that every time I create a new worksheet the color is automatically red.

Do you have any ideas how to get this managed?

Thanks a lot!

Hi there, this is my first post in this forum. I hope you can help me with my problem :)

I've created a little program to solve a problem for my class. This is the first time, I wrote a program with Maple, so please don't laugh. 

I've posted the Maple code below:


restart; randomize():
with(plots): with(plottools): with(LinearAlgebra): with(Statistics): with(MTM):

s:={1=2, 3=2}:



local m, h, adresses, rndmAdrs, omega: omega:=Vector[row](np,s);


for m from 1 to np do
if(omega[m]=0) then
end if


for m from 1 to volfrac*np do

for m from 1 to np -(volfrac*np+nops(s)) do





local m, alle:

alle:=Matrix(nr,np); for m from 1 to nr do


alle[m]:=Realisierung(np,volfrac); od;





I used the Shuffle function from Statistics-package to randomly permutate the components in the Vector adresses. Which works fine. By setting Randomize(); I get randomly results vor this permutation, when I execute the whole worksheet.

But when the "Realisierung" procedure is called in the for loop of the "RealMatrix" procedure, always the same Permutation is calculated.

This leads to the fact, that every row in my matrix looks the same.
Like in the example

2 1 2 2 1
2 1 2 2 1
2 1 2 2 1
2 1 2 2 1
2 1 2 2 1

but the lines should be randmly like

2 1 2 2 1
2 2 2 1 1
2 1 2 1 2
2 1 2 2 1


Obvioulsy the problem is in the randomize()-command. I tried to place it directly after "restart" and directly before the Shuffling is executed.
But I had no succes. 

Maybe one of you can help me?
Would be great!
