A Diagonal Matrix has values on the diagonal entries, and zero on the rest: C =
A Scalar Matrix has equal diagonal entries and zero on the rest: C =
on the diagonal and
on the rest. This is the matrix equivalent of 1. The symbol is I. I =
If you multiply any matrix with the identity matrix, the result equals the original.
(Null Matrix) has only zeros. C =
