Dynare version 4
|
|
================
|
|
|
|
Dynare is now installed on your Debian system in '/usr/lib/dynare'.
|
|
|
|
You can get more information on the web, on Dynare homepage:
|
|
|
|
http://www.dynare.org
|
|
|
|
Or on Dynare Wiki:

|
|
|
Using Dynare with Matlab (R)
|
|
----------------------------
|
|
|
|
Dynare requires Matlab (R) version 6.5 or above. With older versions of Matlab (R),
|
|
it may fail or give unexpected results.
|
|
|
|
To use Dynare, you just have to add the 'matlab' subdirectory of your Dynare
|
|
installation to Matlab (R) path. You have two options for doing that:
|
|
|
|
* Use the addpath command, by typing the following:
|
|
|
|
addpath /usr/lib/dynare/matlab
|
|
|
|
Matlab (R) will not remember this setting next time you run it, and you will
|
|
have to do it again.
|
|
|
|
* Select the "Set Path" entry in the "File" menu, then click on "Add
|
|
Folder...", and select the '/usr/lib/dynare/matlab' directory. Note that you
|
|
SHOULD NOT use "Add with Subfolders...". Apply the settings by clicking on
|
|
"Save". Note that Matlab (R) will remember this setting next time you run it.
|
|
|
|
You can test your installation by typing 'dynare' at the Matlab (R)
|
|
prompt. This should give you an error message complaining that you did not
|
|
specify a MOD file.
|
|
|
|
|
|
Using Dynare with Octave
|
|
------------------------
|
|
|
|
Dynare is now available for Octave, a free clone of Matlab (R) (see
|
|
<http://www.octave.org>).
|
|
|
|
Octave should already be installed on your system, as a dependency of the
|
|
Dynare package.
|
|
|
|
Every time you run Octave, you should type the two following commands:
|
|
|
|
addpath /usr/lib/dynare/matlab
|
|
mark_as_command dynare
|
|
|
|
NOTE: if you don't want to type these two commands every time you run Octave,
|
|
you can put them in a file called '.octaverc' in your home directory. This file
|
|
is run by Octave at every startup.
|
|
|
|
You can test your installation by typing 'dynare' at the Octave prompt. This
|
|
should give you an error message complaining that you did not specify a MOD
|
|
file.
|
|
|
|

|
Dynamic Loadable Libraries
|
|
--------------------------
|
|
|
|
For better performance, some parts of Dynare are written in the C++ language,
|
|
which is faster than standard M-files. These parts are compiled and distributed
|
|
as dynamic loadable libraries (DLL), located in the 'mex' subdirectory of your
|
|
Dynare installation.
|
|
|
|
If the DLL are correctly detected by Matlab (R) or Octave, the following should
|
|
be displayed when you launch Dynare:
|
|
|
|
Configuring Dynare ...
|
|
[mex] Generalized QZ.
|
|
[mex] Sylvester equation solution.
|
|
[mex] Kronecker products.
|
|
[mex] Sparse kronecker products.
|
|
|
|
On the contrary, if DLL are not detected, Dynare will fallback on slower
|
|
alternatives written in M-files, and display the following:
|
|
|
|
Configuring Dynare ...
|
|
[m] Generalized QZ.
|
|
[m] Sylvester equation solution.
|
|
[m] Kronecker products.
|
|
[m] Sparse kronecker products.
|
|
|
|
In this last case, Dynare will run correctly, but with suboptimal speed. There
|
|
could be several reasons for Matlab (R) or Octave failing to detect the DLL:
|
|
|
|
* Your path settings may be wrong. Make sure that the 'matlab' subdirectory of
|
|
your Dynare installation is the only Dynare directory present in the path
|
|
variable.
|
|
|
|
* Your Matlab (R) or Octave version may be incompatible with the provided
|
|
binaries.
|
|
|
|
* You may have a custom M-file in your search path with the same name than a
|
|
DLL, therefore overriding it.
