Matrix Inverse Multiplicative Inverse of a Matrix For a square matrix A, the inverse is written A-1. When A is multiplied by A-1 the result is the identity matrix I. Non-square matrices do not have inverses.Note: Not all square matrices have inverses. A square matrix which has an ...
... a matrix has an inverse : Inverse of a MatrixWe write A-1 instead of 1A because we don't divide by a matrix! And there are other similarities:When we multiply a number by its reciprocal we get 1: 8× 18 = 1 When we multiply a matrix by its inverse we get the Identity...
