I've been implementing a MLE of a garch process to obtain the real values of the parameters in the model. All works fine, but whenever I had the leverage effect variable theta in my code, it gets me Error using barrier - Objective function is undefined at...
Errorusing barrier Objectivefunction is undefined at initial point. Fmincon cannot continue. Errorin fmincon (line 797) [X,FVAL,EXITFLAG,OUTPUT,LAMBDA,GRAD,HESSIAN] = barrier(funfcn,X,A,B,Aeq,Beq,l,u,confcn,options.HessFcn,... Errorin max_sol_ln (line 13) ...
自定义函数有问题。把MY_costfunction()贴出来看一下。
求助!matlab中..[x,y]=fmincon('fun3',x0,[],[],[],[],zeros(14,1),[],'fun4',options)错误使用 barrier (line
