Identity matrix (unity matrix): A square matrix with the diagonal elements equal 1 and remaining elements equal to 0. It is designated by a symbol I. Example: Inverse of a matrix: B is the inverse of A if A B = B A = I. If B is the inverse of A, then A is also the inverse of B. Both matrices are invertible.

A square matrix with ones on the diagonal (diagonal always means from upper left to lower right in a matrix) and zeroes elsewhere is called an identity matrix. We usually denote an identity matrix by In if we need to specify that the matrix is n×n or simply by I if the context dictates the size of the matrix.
