无法求极值的多元函数？
第一次用fmin，简化函数及错误提示如下，看不出问题出在哪里，请各位帮忙fua =
(500*x(3)*x(2)^2-107/10)^2+(25/2*x(2)-9)^2+(1000/89*x(1)-824/89)^2
>> x0
x0 =
0.8240 0.7200 0.0413
>> fminunc(fua,x0)
??? Error using ==> optimfcnchk
If FUN is a MATLAB object, it must have an feval method.
Error in ==> fminunc at 192
funfcn = optimfcnchk(FUN,'fminunc',length(varargin),funValCheck,gradflag,hessflag);
>> fminsearch(fua,x0)
??? Error using ==> fcnchk
If FUN is a MATLAB object, it must have an feval method.
Error in ==> fminsearch at 178
funfcn = fcnchk(funfcn,length(varargin));
回复
这种简单问题建议 help fminunc,help fminsearch, 自己看看相信就能解决．提示：先定义你的函数为inline函数即可．
