A null matrix is a matrix in which every element of the matrix equals 0. It can be of any dimension. Addition and subtraction of a null matrix leaves the original matrix unchanged, multiplication with a null matrix results in another null matrix.

OBS

A zero matrix is sometimes called a trivial matrix. A matrix which has at least one nonzero entry is called a nontrivial matrix or nonzero matrix. (It is not required that all entries be nonzero, just that at least one of them is nonzero!)
