如何在Matlab中以标准表示法求解线性编程? [英] How to solve a linear programing in matlab in canonical representation?

问题描述

是否可以像这样输入matlab字符串:

Is it possible to enter matlab a string like that:

MAX  140 x1 + 160 x2 +x3

SUBJECT TO

2 x1 + 4 x2 <= 28

5x1 + 5.333x2 -500X3 = 0

x1 <= 8

x2 <= 6

END

我已安装的工具箱:

v = ver; setdiff({v.Name}，'MATLAB')'

v = ver; setdiff({v.Name}, 'MATLAB')'

推荐答案

签出 linprog :

f = [140, 160, 1]'; %'
A = [2 4 0];
b = 28;
Aeq = [5 5.3333 -500]
beq = 0
lb = -inf*ones(3,1);
ub = [8, 6, inf]';

x = linprog( f, A, b, Aeq, beq, lb, ub );
