This directory contains matlab and fortran programs for linear programming. There are several examples as well. (It appears that they run well on matlab 5, but have a conflict with matlab 4.) The file simplex.m contains a program that solves the linear programming problem. To use this you can try the following: matlab ex1 simplex The first line invokes matlab. The second line initiates the data contained in the file ex1.m The third line calls the program in file simplex.m You can copy these files to your own matlab directory and run the program there. Note that you will need the file reg.m as well as simplex.m The file pivot.m contains a pivoting program which allows you to decide which column and row to pivot on. You can enter help pivot to get more information. The file main.m is an old version of simplex.m and may contain bugs. Note that there were some conflicts with the new version of matlab. This should have been resolved in simplex.m.
