We say that A is invertible if there is an n × n matrix B such that. AB = I n and BA = I n . In this case, the matrix B is called the inverse of A , and we write B = A − 1 . We have to require AB = I n and BA = I n because in general matrix multiplication is not commutative. bing communications company limited

"In linear algebra, an n-by-n square matrix A is called invertible (also nonsingular or nondegenerate), if there exists an n-by-n square matrix B such that where In denotes the n-by-n identity matrix and the multiplication used is ordinary matrix multiplication. If this is the case, then the matrix B is uniquely determined by A, and is called the (multiplicative) inverse of A, denoted by A . Matrix inversion is the process of finding the matrix … " - Only square matrix has inverse

Web3.1.1 The left inverse and right inverse. The usual matrix inverse is defined as a two-side inverse, i.e., AA−1 = I = A−1A because we can multiply the inverse matrix from the left or from the right of matrix A and we still get the identity matrix. This property is only true for a square matrix A. Web4 de jun. de 2024 · Non-square matrices (m-by-n matrices for which m ≠ n) do not have an inverse.
