【求助】matlab中求多元非线性求极值，出现increase OPTIONS.MaxFunEvals.
【求助】在matlab7.0求一非线性方程极值的问题。代码是
clc
clear
xi=;
Lbnd=;
Ubnd=;
options=optimset;option.=10e1000000000;option.display='off';
= fmincon(@fbmin,xi,[],[],[],[],Lbnd,Ubnd,[],options)
调用的函数是：
function d=fbmin(v)
x1=v(1);x2=v(2);x3=v(3);x4=v(4);
x5=v(5);x6=v(6);x7=v(7);
t= (1-2.62*(1-0.36*(x4./x2).^(-0.56)).^(1.5).*(x4./x2).^(1.16))./x6./x7;
y=(x1./x5).*(x3./(x2-x1)).^0.85;
y=174.42*y.*t.^(0.5) ;
d=abs(y-1.5);
结果为：
Maximum number of function evaluations exceeded;
increase OPTIONS.MaxFunEvals.
x =
0.1070 0.3649 0.1199 0.1234 1.8130 12.0863 0.9039
fx =
4.6185e-014
out =
0
increase OPTIONS.MaxFunEvals.
修改了语句使得option.MaxFunEvals=10e1000000000
但是还是不对~~~
有没有高手能指点一下~~谢谢！
