The variable A is a matrix in Maple. I need to show A, A^2, A^3, ....., A^19, A^20, and that i do by making a for loop:

    for n to 20 do A^n end do

And it works and shows correct results.. 

But i want to show more than just the result of each step in the for loop. 

The result right now is without variable name etc. How can i show more than just the result ? ... 

I have changed the Typesettinglevel to extended.

Hello guys,

I am unfamiliar with maple and have problems with dsolve complex system:

dz*_i/dt=sum(sum(z_i-z_j),j=1..2),i=1..2).

where i not equal to j and z* is conjugate(z).

here is my code:

for i from 1 to 2 do

summ(i)=0

od;

for j from 1 to 2 do

for i from 1 to 2 do

if i <> j then

summ(i)=summ(i)+(z_j(t)-z_i(t));

end if

od;

od

for j from 1 to 2 do

 Hi all,

I'm trying to use the geometry module. I tried the following code:

> with(geometry);
> point(A, xA, xB);
A
> point(B, xB, yB);
B
> line(AB, [A, B]);
line: One of the following conditions must be satisfied xA-xB <> 0 xB-yB <> 0
Error, (in geometry:-line) not enough information: the line is not defined

As you can see, maple is unable to create the line object since the two points can be the same....

Hello,

I have downloaded the quaternion package in Maple but I can't figure out how to plot them. According to the help page I need a package 'with(Plots)' (with a capital P for plots). Has anyone had any success in plotting quaternions? I'd really appreciate some help.

Thank you.

What is the total number of the nonnegative integer solutions of the system
{x+2*y+5*z-10^2012<=0, x+3*y+4*z-10^2012<=0}?
Edit. Bad copy and paste and  the tags.

What is the total number of the natural solutions of the equation
2*x+3*y+5*z+8*t-10^2012 = 0? How to find it with Maple?

Is there some way to shade in the region between the red and blue curves?

implicitplot([y = (1/5)*x^2+5, y = (1/20)*(x-5)*(x+3)*(x-10)+30, x = 2, x = 10], x = 0 .. 12, y = 0 .. 40, color = [red, blue, black, black], thickness = 3)

I tried this, but it doesn't seem to like having the x's and y's in the z range.

Which algorithm does maple follow for singular value decomposition by command 'SingularValues' in LinearAlgebra Package ?  Is it is QRSVD or divide and conquer or any other   .As far as  I know, MATLAB uses QRSVD.

Dear Maplers

I would like to define a component in MapleSim, which is difficult to write with a single equation, but rather it would be defined with a bunch of equations (a procedure). Can it be done programatically, i.e. can I write my own code (procedure) in Maple programming language to define the component? Or should I subdivide the problem to smaller steps (equations) and define a component for each of them? What would be the best way? Could you possibly give an example?
