Dynare for Octave

Porting of Dynare to Octave is under progress. Development is done using Octave version 3.0.

Development of Dynare for Octave

A specific subversion branch has been created under branches/dynare_v4_octave. Note that this branch is supposed to work on both Matlab and Octave (using tests to differentiate between the two when necessary). Please report any failure to run under Matlab.

It is possible to view the differences between Matlab and Octave versions of Dynare by issuing: 

svn diff http://www.cepremap.cnrs.fr/svn/dynare_v4 http://www.cepremap.cnrs.fr/svn/branches/dynare_v4_octave

Note: be aware that recent changes to Matlab version of Dynare may not have been yet merged into the Octave branch, and may thus appear as spurious differences.

Installing Dynare for Octave

Octave

Under Debian "Lenny", install package octave3.0

For Windows, the Cygwin package is quite outdated. You should rather download [http://sourceforge.net/project/showfiles.php?group_id=2888&package_id=40078 precompiled binaries from Octave Forge].

Dynare

If you don't already have a subversion copy of the whole Dynare tree, you should type (under Linux or under Cygwin prompt, assuming you have installed the subversion package): 

svn checkout http://www.cepremap.cnrs.fr/svn/branches/dynare_v4_octave

Running Dynare for Octave

First, you should run Octave.

Under Linux, at the prompt, just type: 

octave

Under Windows, you should have a shortcut already installed in your Start menu.

Then, from Octave, add the path to dynare_v4_octave using the addpath command, as you would under Matlab. It is possible to autoexecute this command at each Octave start by adding it to the .octaverc startup file (under Linux, this file should be put in the home directory; under Windows, it should be put at the root of the user home under Documents and Settings).

At first glance, Octave doesn't accept short syntax when typing dynare command (need to investigate that issue). In other words, to run Dynare on ramst.mod, you need to type: 

dynare('ramst')

rather than: 

dynare ramst

List of issues between Matlab and Octave

  • Warning handling is different between Matlab and Octave, and necessitated some adjustments.

  • Ajustments were obviously necessary where version() function is called

  • Generalized eigenvalues are not implemented as a primitive (i.e. eig(A,B) doesn't exist in Octave). This implied a change in dr1.m

Current status of development

  • Simple deterministic models should work
