请问matlab自定义函数输入参数不足该怎么解决呢？

Question

function F = Fun(x);
F = [-3*x(1)-x(2),
     -x(1)-2*x(2)];
a = [1 1
    1 0
    0 1];
b = [7,5,5];
c1 = [-3 -1];
c2 = [-1 -2];
[x1,g1] = linprog(c1,a,b,[],[],zeros(2,1));
[x2,g2] = linprog(c2,a,b,[],[],zeros(2,1));
g3 = [g1;g2];
[x,fval] = fgoalattain('Fun',rand(2,1),g3,abs(g3),a,b,[],[],zeros(2,1))

想解决的问题如下：

Answer 1

将代码改为如下形式即可：

a = [1 1
    1 0
    0 1];
b = [7,5,5];
c1 = [-3 -1];
c2 = [-1 -2];
[x1,g1] = linprog(c1,a,b,[],[],zeros(2,1));
[x2,g2] = linprog(c2,a,b,[],[],zeros(2,1));
g3 = [g1;g2];

[x,fval]=fgoalattain(@(x)Fun(x),rand(2,1),g3,abs(g3),a,b,[],[],zeros(2,1))

function F=Fun(x)
F = [-3*x(1)-x(2),
     -x(1)-2*x(2)];
end

计算结果：
x =

3.7561
3.2439

fval =

-14.5122
-10.2439
