% Inputs
% - type [string] type of object to be computed
% - arg1 first input argument of called function
% (usually variable list)
% - arg2 second input argument of called function
% (usually variable or shock list)
% - arg3 first input argument of called function
% (nar or FEVD steps)
% - options_ [structure] Dynare structure defining global options.
% - M_ [structure] Dynare structure describing the model.
% - oo_ [structure] Dynare structure where the results are saved.
% - estim_params_ [structure] structure storing information about estimated
% parameters
% Outputs:
% - oo_ [structure] Dynare structure where the results are saved.
