<dl>
<dt><a name="index-set_005fdynare_005fseed"></a>Command: <strong>set_dynare_seed</strong> <em>(<var>INTEGER</var>)</em></dt>
<dt><a name="index-set_005fdynare_005fseed-1"></a>Command: <strong>set_dynare_seed</strong> <em>(`default')</em></dt>

<dt><a name="index-set_005fdynare_005fseed-4"></a>Command: <strong>set_dynare_seed</strong> <em>(`<var>ALGORITHM</var>', <var>INTEGER</var>)</em></dt>
<dd>
<p>Sets the seed used for random number generation. It is possible to set
a given integer value, to use a default value, or to use the clock (by
using the latter, one will therefore get different results across
different Dynare runs). The <code>reset</code> option serves to reset the
seed to the value set by the last <code>set_dynare_seed</code> command. On
MATLAB 7.8 or above, it is also possible to choose a specific
algorithm for random number generation; accepted values are
<code>mcg16807</code>, <code>mlfg6331_64</code>, <code>mrg32k3a</code>, <code>mt19937ar</code>
(the default), <code>shr3cong</code> and <code>swb2712</code>.

<dl>
<dt><a name="index-save_005fparams_005fand_005fsteady_005fstate"></a>Command: <strong>save_params_and_steady_state</strong> <em>(<var>FILENAME</var>);</em></dt>
<dd>
<p>For all parameters, endogenous and exogenous variables, stores
their value in a text file, using a simple name/value associative table.
</p>
<ul>
<li> for parameters, the value is taken from the last parameter
initialization

</li><li> for exogenous, the value is taken from the last initval block

</li><li> for endogenous, the value is taken from the last steady state computation
(or, if no steady state has been computed, from the last initval block)
</li></ul>

<p>Note that no variable type is stored in the file, so that the values
can be reloaded with <code>load_params_and_steady_state</code> in a setup where
the variable types are different.
</p>
<p>The typical usage of this function is to compute the steady-state of a
model by calibrating the steady-state value of some endogenous
variables (which implies that some parameters must be endogeneized
during the steady-state computation).
</p>
<p>You would then write a first <samp>.mod</samp> file which computes the
steady state and saves the result of the computation at the end of the
file, using <code>save_params_and_steady_state</code>.
</p>
<p>In a second file designed to perform the actual simulations, you would
use <code>load_params_and_steady_state</code> just after your variable
declarations, in order to load the steady state previously computed
(including the parameters which had been endogeneized during the
steady state computation).
</p>
<p>The need for two separate <samp>.mod</samp> files arises from the fact that
the variable declarations differ between the files for steady state
calibration and for simulation (the set of endogenous and parameters
differ between the two); this leads to different <code>var</code> and
<code>parameters</code> statements.
</p>
<p>Also note that you can take advantage of the <code>@#include</code>
directive to share the model equations between the two files
(see <a href="Macro_002dprocessing-language.html#Macro_002dprocessing-language">Macro-processing language</a>).

<a name="load_005fparams_005fand_005fsteady_005fstate"></a><dl>
<dt><a name="index-load_005fparams_005fand_005fsteady_005fstate"></a>Command: <strong>load_params_and_steady_state</strong> <em>(<var>FILENAME</var>);</em></dt>
<dd>
<p>For all parameters, endogenous and exogenous variables, loads
their value from a file created with <code>save_params_and_steady_state</code>.
</p>
<ul>
<li> for parameters, their value will be initialized as if they
had been calibrated in the <samp>.mod</samp> file

</li><li> for endogenous and exogenous, their value will be initialized
as they would have been from an initval block
</li></ul>

<p>This function is used in conjunction with
<code>save_params_and_steady_state</code>; see the documentation of that
function for more information.

<a name="dynare_005fversion"></a><dl>
<dt><a name="index-dynare_005fversion"></a>MATLAB/Octave command: <strong>dynare_version</strong> <em>;</em></dt>
<dd>
<p>Output the version of Dynare that is currently being used (<i>i.e.</i>
the one that is highest on the MATLAB/Octave path).
</p>
</dd></dl>

<dl>
<dt><a name="index-write_005flatex_005fdefinitions"></a>MATLAB/Octave command: <strong>write_latex_definitions</strong> <em>;</em></dt>
<dd>
<p>Writes the names, LaTeX names and long names of model variables to
tables in a file named <code>&lt;&lt;M_.fname&gt;&gt;_latex_definitions.tex</code>. Requires the
following LaTeX packages: <code>longtable</code>
</p></dd></dl>

<dl>
<dt><a name="index-write_005flatex_005fparameter_005ftable"></a>MATLAB/Octave command: <strong>write_latex_parameter_table</strong> <em>;</em></dt>
<dd>
<p>Writes the LaTeX names, parameter names, and long names of model parameters to
a table in a file named <code>&lt;&lt;M_.fname&gt;&gt;_latex_parameters.tex</code>. The command writes the values
of the parameters currently stored. Thus, if parameters are set or changed in the steady state 
computation, the command should be called after a <code>steady</code>-command to make sure the 
parameters were correctly updated. The long names can be used to add parameter descriptions. Requires the
following LaTeX packages: <code>longtable, booktabs</code>
</p></dd></dl>

<dl>
<dt><a name="index-write_005flatex_005fprior_005ftable"></a>MATLAB/Octave command: <strong>write_latex_prior_table</strong> <em>;</em></dt>
<dd>
<p>Writes descriptive statistics about the prior distribution to a LaTeX table
in a file named <code>&lt;&lt;M_.fname&gt;&gt;_latex_priors_table.tex</code>. The command writes
the prior definitions currently stored. Thus, this command must be invoked
after the <code>estimated_params</code> block. If priors are defined over the
measurement errors, the command must also be preceeded by the declaration of
the observed variables (with <code>varobs</code>). The command displays a warning if
no prior densities are defined (ML estimation) or if the declaration of the
observed variables is missing. Requires the following LaTeX packages:
<code>longtable, booktabs</code>
</p></dd></dl>

<dl>
<dt><a name="index-collect_005flatex_005ffiles"></a>MATLAB/Octave command: <strong>collect_latex_files</strong> <em>;</em></dt>
<dd>
<p>Writes a LaTeX file named <code>&lt;&lt;M_.fname&gt;&gt;_TeX_binder.tex</code> that collects all TeX output generated by Dynare 
into a file. This file can be compiled using pdflatex and automatically tries to load all required packages. 
Requires the following LaTeX packages: <code>breqn</code>, <code>psfrag</code>,
<code>graphicx</code>, <code>epstopdf</code>, <code>longtable</code>,  <code>booktabs</code>,  <code>caption</code>,
<code>float</code>, <code>amsmath</code>, <code>amsfonts</code>, and <code>morefloats</code>
</p></dd></dl>
