Before you work through this leaﬂet, you will need to know how to ﬁnd the determinantand cofactorsof a 3× 3 matrix. If necessary yo The so-called invertible matrix theorem is major result in linear algebra which associates the existence of a matrix inverse with a number of other equivalent properties. A matrix possessing an inverse is called nonsingular, or invertible. The matrix inverse of a square matrix may be taken in the Wolfram Language using the function Inverse[m. You could calculate the determinant of the matrix which is recursive and then form the adjoined matrix. Here is a short tutorial. I think this only works for square matrices. Another way of computing these involves gram-schmidt orthogonalization and then transposing the matrix, the transpose of an orthogonalized matrix is its inverse To calculate a determinant you need to do the following steps. Set the matrix (must be square). Reduce this matrix to row echelon form using elementary row operations so that all the elements below diagonal are zero.
