Dynare
======
For information about how to use Dynare, you should have a look at the
documentation located in the 'doc' subdirectory of your Dynare installation (you
should have a shortcut in your Start Menu to access it directly).
Beginners should start with the Dynare user guide (under PDF format in
'UserGuide.pdf'). There is also a complete reference manual documenting all
Dynare functions (under HTML format in 'dynare.html/index.html', under PDF
format in 'dynare.pdf').
You can also get more information on the web, on Dynare homepage:
http://www.dynare.org
Or on Dynare Wiki:

NOTE: To uninstall Dynare, simply drag the Dynare installation directory to the
Trash.
Using Dynare with MATLAB (R)
----------------------------
Dynare works on all versions of MATLAB (R) for Intel Macs.
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 (assuming that you have
installed Dynare at the standard location, and replacing '4.x.y' by correct
version number):
addpath /Applications/Dynare/4.x.y/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 '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 (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 also works on top of GNU Octave, a free clone of MATLAB (R) (see
<http://www.octave.org>).
This version of Dynare is compiled for Octave 3.6.2, and may not work
with other versions of Octave. You can download Octave through the Homebrew
package manager:
http://mxcl.github.com/homebrew
Every time you run Octave, you should type the two following commands (assuming
that you have installed Dynare at the standard location, and replacing '4.x.y'
by correct version number):
addpath /Applications/Dynare/4.x.y/matlab
NOTE: 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 ('/Users/USERNAME').
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 shared libraries, located in the 'mex' subdirectory of your Dynare installation.
If the libraries 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.
[mex] Local state space iteration (second order).
[mex] Bytecode evaluation.
[mex] k-order perturbation solver.
[mex] k-order solution simulation.
[mex] Quasi Monte-Carlo sequence (Sobol).
On the contrary, if the libraries are not detected, Dynare will fallback on
slower alternatives written in M-files (which exist for some of the libraries),
and display the following:
Configuring Dynare ...
[m] Generalized QZ.
[m] Sylvester equation solution.
[m] Kronecker products.
[m] Sparse kronecker products.
[m] Local state space iteration (second order).
[no] Bytecode evaluation.
[no] k-order perturbation solver.
[no] k-order solution simulation.
[no] Quasi Monte-Carlo sequence (Sobol).
In this last case, Dynare will run correctly on the basic features,
but with suboptimal speed, and some features will be missing. There
could be several reasons for MATLAB (R) or Octave failing to detect
the libraries:
* 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 as one of
the Dynare libraries, thereby overriding it.
