An implementation for basic LP algorithms

A Matlab implementation for basic Linear Programming algorithms, such as simplex, big M and two phase methods. An implementation for Zoutendijk method as described in 'Nonlinear Programming - Theory and Algorithms by Bazaraa, Sherali and Shetty'. To test Simplex, BigM and Two-phase: run 'scr_simplex.m'. To test Zoutendijk: run 'scr_zoutendijk .m'
