Invertible matrix and its inverse. A square matrix A is called invertible or non-singular if there exists a matrix B such that AB = BA = I n, where I n is the n×n identity matrix with 1s on the main diagonal and 0s elsewhere. If B exists, it is unique and is called the inverse matrix of A, denoted A −1. Definite matrix
This matrix has no inverse because the columns are not linearly independent. This means if you row reduce to try to compute the inverse, one of the rows will have only zeros, which means there is no inverse.

Inverse of a Matrix Matrix Inverse Multiplicative Inverse of a Matrix. When A is multiplied by A-1 the result is the identity matrix I. Non-square matrices do not have inverses.
The inverse is the transpose of the matrix where each element is the determinant of its minor (with a sign calculation) divided by the determinant of the whole. To calculate this we can follow these steps: Calculate the minor for every matrix element. Form the cofactor matrix from the minors with signs.
