我在matlab2011b中输入lb=0;ub=inf;tic; options=optimset('Algorithm','levenberg-marquardt'); [para,resnorm,residual,exitflag,output]=lsqnonlin(@(para)paraoptifun(para,wt0exp,wtexp,T),para,lb,ub,options);,出现Undefined function 'paraoptifun' for input arguments of type 'double'.
Error in @(para)paraoptifun(para,wt0exp,wtexp,T)
Error in lsqnonlin (line 199) initVals.F = feval(funfcn{3},xCurrent,varargin{:});
Caused by: Failure in initial user-supplied objective function evaluation. LSQNONLIN cannot continue.是什么原因啊 ?
