please, I need your help to solve this error.

Error using DSGE_KDM.driver
Error: File: driver.m Line: 378 Column: 1

Error in dynare (line 278)
evalin(‘base’,[fname ‘.driver’]);

DSGE_KDM.mod (14.9 KB)

There is an invisible unicode character in your third line. Delete the first three lines and you will get a more expressive message about an object not being defined.

is relevant in this case.

Thanks for your help, now I have other errors:
Error using DSGE_KDM_steadystate
Too many input arguments.

Error in evaluate_steady_state_file (line 49)
[ys,params1,check] = h_steadystate(ys_init, exo_ss,M,options);

Error in evaluate_steady_state (line 254)
[ys,params,info] = evaluate_steady_state_file(ys_init,exo_ss,M, options,steadystate_check_flag);

Error in DSGE_KDM.driver (line 447)

Error in dynare (line 278)

Do you use Dynare 5?

I use dynare versuin 5.4

Then you are using an old steady state file. See
