这个代码，怎么跑不出来，我想用它生成三维图

[code][X,Y] = meshgrid(6:12,8:16);
F = X.*Y;
C = true(size(X));
for i = 1:numel(X)
    n = X(i);
    y = Y(i);
    c = 0;
    for k = 1:1:n
        c = c+(1849000*y + 8600*(k -1 )* x( 2 )^2 + 10*( k - 1 )^2 * x(2)^3)/ ...
            ((400+(k-1)*x(2))* (24900+860*(k-1)* x(2)+(k-1)^2 * x(2)^2))
    end
    C(i) = 24-c<=0;
end
minf = min(F(C));
I = find(minf==F&C);
x = X(I)
y = Y(I)
fmin = x*y[/code]

Answer 1

代码已经修改，供参考：

[X,Y] = meshgrid(6:12,8:16);
F = X.*Y;
C = true(size(X));
for i = 1:numel(X)
    n = X(i);% 我这里的n就是x(1)
    y = Y(i);% 我这里的y就是你的x(2)
    c = 0;
    for k = 1:1:n
        c = c+(1849000*y + 8600*(k -1 )*y^2 + 10*( k - 1 )^2 * y^3)/ ...
            ((400+(k-1)*y)* (24900+860*(k-1)* y+(k-1)^2 *y^2));
    end
    C(i) = 24-c<=0;
end
minf = min(F(C));
if(isempty(minf))
    fprintf('无解\n')
else
    I = find((minf==F)&C);
    x = X(I);
    y = Y(I);
    fmin = x*y;
    fprintf('在x=%d,y=%d处目标函数有最小值%d\n',x,y,fmin)
end

答案是无解
