"A" cannot be a matrix of strings, because this is not valid in Matlab. Do you mean a cell string?

If you have the Symbolic Toolbox, you can do this:
str = sym('str_%d', [1 n]);
A = [str(1), str(2)
str(1), str(4)];
subs(A, str, [1 2 17 4])
you might even be able to refer to str_1 directly in A; I would need to test that.
