\section *{Preface}

IRIS is a Matlab\raisebox{0.3em}{\tiny\textregistered} toolbox for macroeconomic modelling. It is free, open-source software distributed under BSD licence terms. The current version of IRIS runs in Matlab R2009a or later.

IRIS has been designed as an integrated and extensible package. It includes not only objects and functions directly related to modelling itself, but also provides support for bulding nad implementing model-aided forecasting and policy analysis systems, and for model-based economic research. This includes multivariate time series analysis (VARs, BVARs, FAVARs), basic time series and database management, and reporting.
