% Inputs
% z [n_var*(nshock+2)*nperiods] shock decomposition array, see shock_decomposition.m for details
% shock_names [endo_nbr*string length] shock names from M_.exo_names
% endo_names [exo_nbr*string length] variable names from M_.endo_names
% i_var [n_var*1] vector indices of requested variables in M_.endo_names and z
% initial_date [dseries object] first period of decomposition to plot
% DynareModel [structure] Dynare model structure
% DynareOptions [structure] Dynare options structure
