Failure in initial user-supplied objective function evaluation. FMINCON cannot continue.

Kindly advise on the error I am getting. I am trying to run the fmincon code for my portfolio optimisation but unable to do so. Please tell me how to get the distribution of my portfolio as well. Thanks

% column vector for initial weight w3 = fmincon(@(w)compute_pvar (w, C_is *252) , w0 , [] , [] , Aeq , beq , [] , [] , [] , options); pvar = compute_pvar (w3 , C_is *252) ; fprintf ('The minimum portfolio variance is %.4f.\n', sqrt ( pvar )) ;

How should we be able to answer your question without seeing your function "compute_pvar" ?

Best wishes
