WebAn identity matrix would seem like it would have to be square. That is the only way to always have 1's on a diagonal- which is absolutely essential. However, a zero matrix could me mxn. Say you have O which is a 3x2 matrix, and multiply it times A, a 2x3 matrix. That is defined, and would give you a 3x3 O matrix.
