These are the ranges where inverse of matrix A will be computed. For example if you transpose a 'n' x 'm' size matrix you'll get a new one of 'm' x … It will find the eigenvalues of that matrix, and also outputs the corresponding eigenvectors. The inverse of a matrix is expressed by A -1. A new matrix is obtained the following way: each [i, j] element of the new matrix gets the value of the [j, i] element of the original one. We start with the matrix A, and write it down with an Identity Matrix I next to it: (This is called the \"Augmented Matrix\") Now we do our best to turn \"A\" (the Matrix on the left) into an Identity Matrix.
