that problem is solved as I have changed the upper and lower bounds.  
now error is:  
Output argument “IRF\_model” (and maybe others) not assigned during call to “IRF\_matching\_objective”.  
Error in IRFNEW (line 285)  
[fval,IRF\_model]=IRF\_matching\_objective(x\_opt\_hat,IRF\_empirical,IRF\_weighting);
