Question

matlab解非线性规划问题出错

题目

第一个M文件代码
function f=fun(x);
f=exp(x(1))*(4*x(1)^2+2*x(2)^2+4*x(1)*x(2)+2*x(2)+1);
第二个M文件代码
function [g,ceq]=my(x);
g=[1.5+x(1)*x(2)-x(1)-x(2);-x(1)*x(2)-10];
ceq=[];
第三个M文件代码
x0=[-1;1];
A=[];b=[];
Aeq=[1 1];beq=[0];
vlb=[];vub=[];
[x,fval]=fmincon('fun',x0,A,b,Aeq,beq,vlb,vub,'my')
运行后

这个什么意思 ？？应该怎么解决啊

Answer 1

提示的意思是：
警告：大型方法（信任域）不适合解当前类型的问题，换用中型解法（直线搜索）。
>在fmincon 的260行
在funmy的5行
优化中止：一阶优化测度小于选项TolFun，并且，最大约束的违犯小于选项TolCon

有效的不等式（在选项TolCon = 1e-006之内）。
