makeglpk.m

This routine calls the glpk library to solve a LP/MIP problem. A typical LP problem has following s

function varargout = makeglpk(varargin)
% MAKEGLPK M-file for makeglpk.fig
%      MAKEGLPK, by itself, creates a new MAKEGLPK or raises the existing
%      singleton*.
%
%      H = MAKEGLPK returns the handle to a new MAKEGLPK or the handle to
%      the existing singleton*.
%
%      MAKEGLPK('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in MAKEGLPK.M with the given input arguments.
%
%      MAKEGLPK('Property','Value',...) creates a new MAKEGLPK or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before makeglpk_OpeningFunction gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to makeglpk_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
