matlab codes of fattailed_garch by Ucsd_garch but have this errors

hi dear friends i run matlab codes of fattailed_garch by Ucsd_garch but have this errors Warning: The default trust-region-reflective algorithm does not solve problems with the constraints you have specified. FMINCON will use the active-set algorithm instead. For information on applicable algorithms, see Choosing the Algorithm in the documentation. > In fmincon at 504 In fattailed_garch at 125 Warning: Your current settings will produce an error in a future release. > In fmincon at 514 In fattailed_garch at 125 Error using feval Undefined function 'fattailed_garchlikelihood' for input arguments of type 'double'. Error in fmincon (line 635) initVals.f = feval(funfcn{3},X,varargin{:}); Error in fattailed_garch (line 125) [parameters, LLF, EXITFLAG, OUTPUT, LAMBDA, GRAD] = fmincon('fattailed_garchlikelihood', startingvals ,sumA , sumB ,[] , [] , LB , UB,[],options, data, p , q, errortype, stdEstimate, T); Caused by: Failure in initial user-supplied objective function evaluation. FMINCON cannot continue. anybody can help me what's the problem? thanks

Sima - this type of error, Undefined function 'fattailed_garchlikelihood' for input arguments of type 'double', either means that you do not have this function (or it isn't in the MATLAB search path) or it is being passed invalid input parameters. In the Command Window, type

 which fattailed_garchlikelihood -all

What do you observe? Since I don't have this code, I see the following

 'fattailed_garchlikelihood' not found.

thanks dear geoff when copy matlab codes in current folder in matlab and run. i get the solution. :)

Sima - or just add the folder with the code to fattailed_garchlikelihood to the MATLAB search path.

ok. thanks :)
