Subscripted assignment dimension mismatch

Hello,

I tried to ran a code but when it got to the parallel loop below, it gave me the error message "Subscripted assignment dimension mismatch"

fvals=zeros(size(Data.S,1),1); %initialize vector for function values
      object=Data.objfunction; %objective function handle
      Samples=Data.S;  %points to be evaluated in parallel
      Tfeval=zeros(size(Data.S,1),1);  %initialize vector for evaluation times

parfor ii = 1:size(Data.S,1)  %parallel for
          fevalst=tic; %record function evaluation time 
          fvals(ii,1)=feval(object,Samples(ii,:)); %expensive function evaluations
          Tfeval(ii,1)=toc(fevalst);
end

Please what could be the problem?

Your call to feval() probably returns multiple numbers instead of one.

Next time include the WHOLE error message, not just a tiny part snipped out of it. You can save time in getting to a correct solution/Answer that way.
