1. 2.5 The Gauss-Jordan Method for Calculating Inverses Finding Inverses When the matrix is a 2 x 2, the inverse is easy to find using the determinant. What if the inverse of a larger square matrix needs to be found? That is when G-J needs to be performed with the original matrix and Identity matrix side by side. How this works… You set up the process to look like: Then do row manipulations until it looks like: What is the inverse of an inverse matrix?
