[c,ceq] = ....
c=...
ceq=[a;
b;
c]
是这样么? |

"According to research published in the China Economic Quarterly by Brad
Setser, a specialist in sovereign wealth at the Council on Foreign Relations
in New York," however, the real reserve of China is "currently worth
roughly $2,500bn" or $2.5 trillion.

发帖数: 351 | 5 用 fmincon 优化
x = fmincon(&myfun,x0,[],[],[],[],[],[],&mycon)
非线性的约束条件做成函数.
function [c,ceq] = mycon(x)
c = ... % Compute nonlinear inequalities at x.
ceq = x(1)+x(2)-b % Compute nonlinear equalities at x.
现在的问题是，这个约束条件mycon里有一个需要不断改变的参数b。怎么能把这个参数
从外面传到这个约束条件的函数mycon里面。 |
