This version does NOT implement the Revised Simplex Method and it uses neither any implicit inverse update schemes nor any sophisticated entering variable selection scheme. Integer Mode eliminates decimals and fractions in all the tableaus (using the method described in the simplex method tutorial) and displays the solution as fractions. These files should perform well on 'small' problems where A is m x n with m,n < 100. The file UNBOUND.MAT contains an LP that has an unbounded, feasible ray along which the objective value will tend to infinity. The file PHIDEGEN.MAT contains an LP for which phase I produces a degenerate solution, but for which the original LP has an optimal solution. The file INFEAS.MAT contains an LP that is infeasible. Klee for which the m x 2m system of constraints requires 2^m - 1 iterations (half during phase I and half during phase II). These particular LP's are of a type attributed to V. The files OPT1.MAT, OPT2.MAT and OPT3.MAT contain matrices for LP's possessing an optimal solution. where LHS includes the variable.And the pre-assumed constraint is that all the variables are +ve A 1 2 3 4 0 0 0 0 3 2 1 1 0 10 0 2 5 3 0 1 15 C 0 0 0 na ma size(A) nc mc size(C) check for matrix C if nc 1 disp('Pls check the given objective. In addition, there are a number of mat-files containing examples. Simplex Method MATLAB Code: function val mat simplexmin(A,C ) for optimizing given condition 'C' with constraints 'A' A is an augmented matrix All the constraints are should be of the form L.H.S. The three files LINPROG.DOC, PHASEI.DOC and PHASEII.DOC are fully documented versions of the m-files LINPROG.M, PHASEI.M and PHASEII.DOC are fully documented versions of the m-files LINPROG.M, PHASEI.M and PHASEII.M. If you try to solve these you will see that code doesn't have an answer and I want to know what exactly must change in order to work.This directory contains a suite of files for performing the standard two phase simplex method on linear programming problems. Working Example and not Working Examples are in the picture below : In some examples it's not working and I can't find what the problem is. I have a problem with my MATLAB code that solves linear equations with two phase simplex method.
