 Zero matrix

A matrix all of whose entries are zero. It is the additive identity among matrices of the same dimensions and represents the zero linear map in any choice of bases.

A zero matrix, also known as a null matrix, is a matrix in which all of its elements are equal to zero. It can come in various sizes, such as 2x2, 3x3, or any other \( m \times n \) dimensions, where \( m \) is the number of rows and \( n \) is the number of columns.
