I am calculating the optimum conditions for milling process but its showing the following error on running "Failure in initial objective function evaluation. FMINCON cannot continue."Can anyone please hhelp me in solving it.I have attached the files in it too.The first file reads the data from an excel file and second file has the population balance method which has to be minimized.
The error is shown:
Output argument "y" (and maybe others) not assigned during call to "Pbmsearch".
Error in fmincon (line 567)
initVals.f = feval(funfcn{3},X,varargin{:});
Error in parameter (line 24)
[x,fval,exitflag]=fmincon(@Pbmsearch,x0,[],[],[],[],lb,ub);
Caused by:
Failure in initial objective function evaluation. FMINCON cannot continue.

The problem has nothing to do with fmincon. You must first make sure that your objective function runs without errors at x0.
