Question

有那位高手能给我编几个数学建模matlab程序，非常感谢，急用

1.
z=min{100*X+40*(y1+y2+y3+y4+y5)};
y1+y2+y3+y4+y5<=3;
X+y1>=4;
X+y1+y2>=3;
X+y1+y2+y3>=4;
x1+y1+y2+y3+y4>=6;
x2+y2+y3+y4+y5>=5;
x1+x2=X;
X+y3+y4+y5>=6;
X+y4+y5>=8;
X+y5>=8;
2.
z=min(100*X);
X>=4;
X>=3;
X>=4;
x1>=6;
x2>=5;
x1+x2=X;
X>=8;
3.
z=min{100*X+40*(y1+y2+y3+y4+y5)};
y1+y2+y3+y4+y5<=3;
X+y1>=4;
X+y1+y2>=3;
X+y1+y2+y3>=4;
x1+y1+y2+y3+y4>=6;
x2+y2+y3+y4+y5>=5;
x1+x2=X;
X+y3+y4+y5>=6;
X+y4+y5>=8;
X+y5>=8;

这类线性规划问题用lingo解决吧，比用matlab快多了。
