The same result occurs when the order of the matrix and its inverse is reversed. A matrix $$$ A $$$ has a right inverse if another matrix exists, say $$$ C $$$, such that the result is the identity matrix when $$$ C $$$ is multiplied by $$$ A $$$ from the right, i. #. If a is not square or inversion fails. The most suitable for 2x2 or 3x3 matrix sizes is the cofactor method which necessitate to calculate the determinant of the matrix detM det M and the transposed cofactor matrix (also called adjugate matrix adj(M) adj ( M) ): M −1 = 1 detM (cof(M . matrix inverse of 3x3 matrix.
