Defining matrix of functions

[Geraud]

Hi,

I would like to create a matrix of functions (eg F(t)) by defining every component as a function of the indexes (eg Fp,q=p+q .

The thing is I cannot do it entering "F(t)pq=..." ("the left side cannot be defined(...)")

Has someone a solution ?

Thanks in advance,

Géraud

I'm not sure I understand what you are trying to do - can you give a bit more detail?

Doesn't F(t,p,q):=whatever work?

Then say

t:15
p:0;5
q:0;5

Result[p,q:F(t,p,q)

will create a 6x6 array of answers based on F, t, and the location in the array

Cheers

Try using the build in MathCad function matrix(m,n,F)

This creates a matrix in which the ij[sup]th[/sup] element contains F(i,j).
[sub] where:
p= 0,1..m-1 & q=0,1.. n-1.[/sub]

This has a limit since the argument "F" is defined as a function of two variables only.

Result=matrix(m,n,F)

If that do not work for your application,try using he programming function in MathCad.

Thank you very much for helping me, I am going to apply your solutions.
