function b = isauxiliary(var, types)
|
|
|
|
% Returns true if var is an auxiliary variable.
|
|
%
|
|
% INPUTS
|
|
% - var [string] Name of the variable.
|
|
% - types [integer] vector of type of auxiliary variables.
|
|
%
|
|
% OUTPUTS
|
|
% - b [logical]
|
|
%
|
|
% REMARKS
|
|
%
|
|
% Types for auxiliary variables are as follows:
|
|
%
|
|
% - 0, Lead on endogenous variable (substitute for endo leads >= 2)
|
|
% - 1, Lag on endogenous variable (ubstitute for endo lags >= 2)
|
|
% - 2, Lead on exogenous variable (ubstitute for exo leads >= 1)
|
|
% - 3, Lag on exogenous variable (substitute for exo lags >= 1)
|
|
% - 4 Expectation (substitute for Expectation Operator)
|
|
% - 5, Diff forward (substitute for the differentiate of a forward variable)
|
|
% - 6, Multipliers for FOC of Ramsey Problem
|
|
% - 7, currently not used, see SymbolTable.hh
|
|
% - 8, Variable for Diff operator
|
|
% - 9, Lag on Diff
|
|
% - 10, Variable created when diff was taken of unary operator (log, exp)
|
|
% - 11, Lead on Diff
