求助 怎么总是这个界面啊

改过 还是不对嘛
??? Error using ==> gads\private\makeState
GA cannot continue because user supplied fitness function failed with the following error:
Error: File: g:\Program Files\MATLAB71\work\my_fun.m Line: 1 Column: 9
Unbalanced or misused parentheses or brackets.

Error in ==> gads\private\galincon at 141
state = makeState(GenomeLength,FitnessFcn,options);

Error in ==> ga at 257
[x,fval,exitFlag,output,population,scores] = galincon(FUN,GenomeLength,Aineq,Bineq,Aeq,Beq,LB,UB,options);

Error in ==> F at 6
[x,fval] = ga(FitnessFunction,numberOfVariables,[],[],[],[],LB,UB)

[pslpsl]

这是完全调好后的代码，在MATLAB7.1通过：

 
function ga_solmy_fun

FitnessFunction = @my_fun;
numberOfVariables=2;
LB=[-10 -10];
UB=[10 10];
%没有额外约束 所以MutationFcn参数没有设定 
%求解时会有警告 可以忽略该警告
options=gaoptimset('TolFun',1e-015);
[x,fval] = ga(FitnessFunction,numberOfVariables,[],[],[],[],LB,UB,[],options)
function y = my_fun(x)
y = (cos(2*x(1)+1)+2*cos(3*x(1)+2)+3*cos(4*x(1)+3)+4*cos(5*x(1)+4)+...
    5*cos(6*x(1)+5))*(cos(2*x(2)+1)+2*cos(3*x(2)+2)+3*cos(4*x(2)+3)+...
    4*cos(5*x(2)+4)+5*cos(6*x(2)+5));

求得函数最小值为-186.7左右
