Incomplete or misformed expression or statement 出错求助
麻烦楼主大哥帮帮我吧!fuctionF=mymfun(x)f(1)=0.5*a.*exp(-0.25*pi*(x-b).^2);
f(2)=sqrt(1+(0.25*pi*a.*(x-b)).^2.*exp(-0.5*pi*(x-b).^2);
sym x
F(1)=quad(f(1),0,inf);
F(2)=quad(f(2),-inf,inf);
F=;
然后我在Command里引用
>> x0=[-1000000;1000000];
>> options=optimset('Display','iter');
>> =fsolve(@opt30_5o,x0,options)
??? Error: File: opt30_5o.m Line: 3 Column: 57
Incomplete or misformed expression or statement.
Error in ==> fsolve at 180
fuser = feval(funfcn{3},x,varargin{:});
怎么老出错?这是怎么回事?

f(2)=sqrt(1+(0.25*pi*a.*(x-b)).^2.*exp(-0.5*pi*(x-b).^2);漏了一个括号
这位大哥,我改了,可还不行啊!还得求求你帮帮忙啊!
fuctionF=mymfun(x)f(1)=0.5*x(1).*exp(-0.25*pi*(x-x(2)).^2);
f(2)=sqrt(1+(0.25*pi*x(1).*(x-x(2))).^2.*exp(-0.5*pi*(x-x(2)).^2));

Warning: feval on script names will not work, or may work differently,
in a future version of MATLAB.To make your code insensitive to any change
and to suppress this warning message:
- Either change the script to a function.
- Or use eval instead of feval.
The script file in question is opt30_5o.

还是不行,这回我跟蒙了,我是个新手,不太会,谢谢了! 原帖由 wangdianqun 于 2008-5-6 17:43 发表 http://www.chinavib.com/forum/images/common/back.gif
