Thus, if the rank of an NxM matrix is less than min (N,M), then the matrix is singular. Here are a couple of tests: rank (M) ans = 3 rank (.0001*eye (100)) ans = 100. So rank is able to tell us that the 4x4 magic square is singular, but our scaled identity matrix is not singular. copycat taco john\u0027s potato oles
