灵敏度分析 使用MATLAB编写
实验二、线性规划的灵敏度分析
实验目的
1. 线性规划求解的单纯形法的灵敏度分析的编程实现
2．掌握使用matlab、Lingo、Excel的规划求解功能求解，并利用“敏感性报告”进行分析。
(二)实验内容
课本例1 解的灵敏度分析
(1)：调用单纯形程序：
function [x,z,flg,sgma]=simplexfun(A,A1,b,c,m,n,n1,cb,xx)
% A,b are the matric in A*x=b
% c is the matrix in max z=c*x
% A1 is the matric in simplex table
% m is the numbers of row in A and n is the con number in A
% n1 is the nubers of artificial variables,and artificial variables are default as the last % n1 variables in x.
% cb is the worth coefficient matrix for basic variables
% xx is the index matrix for basic variables
% B1 is the invers matrix for the basic matrix in simplex table.The initial
% matrix is default as the last m con in the matrix A.
x=zeros(n,1);
z=0;
B1=A1(
