These are questions asked by Alger


is it possible to remove this warning and not to show it when executing a procedure ? 

Warning, `AzIII` is implicitly declared local to procedure `lisse`


I have functions like

g := (y, t)->sin(y(t))

diff(g(y, t), t) # ok

How to determine the derivative below with maple :

diff(g(y, t), y(t))



Is it possible to use the command MatrixFunction with two matrices as:


A := Matrix([[-13, -10], [21, 16]]); B := Matrix([[3, 0], [21, 16]]);

BesselY(A,B) ?

In the maple help we can do the calculation only for one matrix as:

MatrixFunction(A, sin(x), x);

Thank you

Hi all,

I write this code with some matricial calculations.

There are two important parameters N and Digits (in red in the code).

For N=8, I can do the calculation with Digits=10. For N=10, to get the results (without overflow), I should give Digits=30.

I want to do the calculation for N=100 and higher.

I do not know how to do this. I have a PC with 4G of RAM.

Thank you


Hi all,

I have this matrix for example:

A := <<1,2>|<3,4>>;

How to determine: 2^A

Thank you
