有没有大佬会用lingo或者matlab写这个的吗（就是图片那个第二个函数关系式求一个最优解p既最大利润时，w,x,y,z的量，x,y,zw结果均为正整数）（p是价格，i是种类，x,y,z,w均为常数）！！！！！
这个是我写的，一直运行不对
sets:
factory/1..8/:x;
row/1..8/:y;
plane/1..8/:p;
reatrant/1..99/:w;
endsets
data:
p=40,
40,
28,
22.5,
25,
40,
40,
45;
enddata
d=@sum(factory(j):x(j));
e=@sum(row(l):y(l));
a=d+e;
b=@sum(factory(j):x(j))@sum(plane(k):p(k));
c=@sum(row(l):y(l))@sum(plane(k):p(k));
l=k;
j=l;
@gin(x(j));
@gin(y(l));
max=3301.67w(i)+15(b+c)-6247.91;
118.245w(i)+0.9a<=1759.715;
0<=w(i);
w(i)<=20;
d<=300;
d>=0;
e<=300;

@gin(w(i));
