How to solve error in fmincon ?

Hi,

what I'm doing wrong so that it displayes error after my specification:

options = optimset('Display','off','Algorithm','active-set');
parameters=fmincon(@SMM2optimconstraint, [10, 0.5, 50, 1.55], A, b, Aeq, beq, lb, ub, options);

Error is:

Error using optimfcnchk (line 286)
NONLCON must be a function.

Error in fmincon (line 436)
   confcn = optimfcnchk(NONLCON,'fmincon',length(varargin),funValCheck,flags.gradconst,false,true);

Thanks.

You skipped the nonlcon argument. If you have no nonlinear constraints, be sure to pass [] as below.

parameters=fmincon(@SMM2optimconstraint, [10, 0.5, 50, 1.55], A, b, ...
                   Aeq, beq, lb, ub, [], options);
