Problem 2: write a matlab function that implements the simplex method. the first line of your .m file should read as follows: function [xsol, optimalobjective, basisfinal]=simplextwoyourname(a, b,c) and it should solve linear programs of the form min c t x s. t. ax = b, x ≥ 0 via simplex method, finding a starting basis with first phase of the two phase method and then solving the problem of interest with the second phase. your matlab function should output the optimal solution, the optimal objective function value, and the final basis that corresponds to the optimal basic feasible solution
