You need to add the matlab
subdirectory of your Dynare
installation to MATLAB® path. You have two options for doing that:
Using the addpath command in the MATLAB® command window:
Under Windows®, assuming that you have installed Dynare at the standard location, and replacing "4.x.y" by correct version number, type:
addpath c:\dynare\4.x.y\matlab
Under Debian GNU/Linux or Ubuntu, type:
addpath /usr/share/dynare/matlab
MATLAB® will not remember this setting next time you run it, and you will have to do it again.
Via the menu entries:
Select the "Set Path" entry in the "File" menu, then click on "Add
Folder...", and select the matlab
subdirectory of your Dynare
installation. Note that you should not use "Add with Subfolders...". Apply
the settings by clicking on "Save". Note that MATLAB® will remember this
setting next time you run it.
You need to add the matlab
subdirectory of your Dynare
installation to Octave path, using the addpath at the Octave command prompt.
Under Windows®, assuming that you have installed Dynare at the standard location, and replacing "4.x.y" by correct version number, type:
addpath c:\dynare\4.x.y\matlab
Under Debian GNU/Linux or Ubuntu, there is no need to use the addpath command; the packaging does it for you.
If you are using an Octave version strictly older than 3.2.0, you will also want to tell to Octave to accept the short syntax (without parentheses and quotes) for the dynare command, by typing:
mark_as_command dynare
If you don't want to type this command every time you run Octave,
you can put it in a file called .octaverc
in your home directory (under Windows® this will generally by c:\Documents and Settings\USERNAME\
). This file is run by Octave at every startup.
You should be very careful about the content of you MATLAB® or Octave path. You can display its content by simply typing path in the command window.
The path should normally contain system directories of MATLAB® or Octave, and some subdirectories of your Dynare installation. You have to manually add the matlab
subdirectory, and Dynare will automatically add a few other subdirectories at runtime (depending on your configuration). You must verify that there is no directory coming from another version of Dynare than the one you are planning to use.
You have to be aware that adding other directories to your path can potentially create problems, if some of your M-files have the same names than Dynare files. Your files would then override Dynare files, and make Dynare unusable.
