The inverse of a matrix can only be found in the case if the matrix is a square matrix and the determinant of that matrix is a non-zero number. Set the matrix (must be square) and append the identity matrix of the same dimension to it. Multiplying a matrix by its inverse is the identity matrix. Here r = n = m; the matrix A has full rank. In linear algebra and statistics, the pseudo-determinant is ... this comparison can be undertaken by using a combination of the ranks of the matrices and their pseudo-determinants, with the matrix of higher rank being counted as "largest" and the pseudo-determinants only being used if the ranks are equal.
