The Identity Matrix :
When dealing with matrix computation, it is important to understand the identity matrix. We can think of the identity matrix as the multiplicative identity of square matrices, or the one of square matrices. Any square matrix multiplied by the identity matrix of equal dimensions on the left or the right doesn't change. The identity matrix is used often in proofs, and when computing the inverse of a matrix.
