求助 fmincon的问题

wucha=sqrt(((D(1,:)*-d(1)))^2+((D(2,:)*-d(2)))^2+((D(3,:)*-d(3)))^2+((D(4,:)*-d(4)))^2+((D(5,:)*-d(5)))^2+((D(6,:)*-d(6)))^2)
以上为m文件
运行以下内容：
x0=;
lb=;
ub=;
=fmincon(@wucha,x0,[],[],[],[],lb,ub)
出现的错误：
??? Error using ==> fmincon at 504
FMINCON cannot continue because user supplied objective function failed with the following error:
Output argument "f" (and maybe others) not assigned during call to "C:\Documents and Settings\Administrator\My
Documents\MATLAB\wucha.m (wucha)".
那位高手能帮我看看怎么改一下，拜谢~ 找到原因了
