Sorry Greg, I didn't want to give the impression that I'm not trying! I'm just a bit confused about exactly what this question is asking. Any thoughts to clarify the procedure (not the exact code) would be appreciated :)

Hey Rose, since the size of your matrix is going to be 4x4, you will need to do the following to achieve your goal.

1. Initialize A to a 4x4 zero matrix since that's how much space you need.
 N = 4; this is the number of rows
 M = 4; number of columns
 A = zeros(N,M); % 4x4 matrix
2. write your double for loops
for i = 1 : N
    for j = 1: M
      write your code here (It will be just a single line code)
      read about how for loop works, it is one of the basis of programming.
    end
end
