Solving Matrices

This function makes an imagesc-like plot for two matrices with equal dimensions, in which each each cell of the plot is split diagonally with the upper triangle of cell (i,j) in the plot representing the Matrix1(i,j) and the lower triangle representing Matrix2(i,j).

The m-file finds the elimination matrices (and scaling matrices) to reduce any A matrix to the identity matrix using the Gauss-Jordan elimination method without pivoting. Using the matrices gotten it computes the inverse of the A matrix.

This file contains the example programs and other information for the book Solving ODEs with MATLAB by L.F. Shampine, Ian Gladwell, and Skip Thompson.
