Program Matrix

Program MATRIX by R. L. Norton

This program is a general linear system solver that allows the on-screen input of the matrix of equation coefficients and a vector of constant terms for up to 20 linear equations. It then solves the equation set using a modified Gauss-Jordan algorithm with partial pivoting. The original matrix and vector of constant terms can be re-shown at any time or the solution matrix and vector can be viewed after solution. Labels may be input for all variables. Results may be printed to the screen, to a printer, or to a tab-delimited text file for import to a spreadsheet program.

This program is provided as a free bonus with the purchase of any other program from this website.
