I'm trying to use function handle with arrays. My objective is to create a function which picks a particular element of one dimensional row matrix. It need to output the particular element when I pass matrix and index as arguments. I know there are other ways to do this, but I'm very much interested to see whether this task can be done by function handle or not
Thanks
syms I t
G = matlabFunction(I(t))
A = [1 2 3];
G(A,1)

Not really sure how the code you posted, with syms and matlabFunction is connected to what you are asking, but this function should do what you ask:
f = @(x,idx) x(idx)
