To perform this for all elements of the input array you should learn how to write vectorized code, which is much neater, faster and less buggy, and also learn how indexing works.

B = input('Enter a matrix: ');
B(B<1 | B>29) = 29;
V = ['A':'Z','.? '];
V(B)

When this code is run it produces this in the command line:

Enter a matrix: [1,2,0,3,27;4,28,5,29,6]
ans =
AB C.
D?E F
