how do I index within symfun matrix?

syms A(t) [20,300];

%I want to use A(i,j)=f(t)

Answer 1

[Torsten]

syms f(x) [1 2]
f

f(x) = 

f(1)

ans = 

Therefore what it created was a single function that has an array result. f(1) is interpreted as applying argument 1 to each of the functions inside the array, instead of as indexing the first location in the array.

In short: What you want is impossible in MATLAB.
