<H3>Synopsis</H3>
<p>Print a brief description of the node data in a field.</p>
<HR>
<p>
<pre>
module nstats_raw <src_file="nstats/node_stats_vxp.c",
c_src_files="nstats/node_stats.c cp_utils/avs_err.c

<H3>Description</H3>
<p>nstats_raw prints a brief description of the node data in a uniform
field. The information includes the field's dimensions, number of nodes,
and for each component, the vector length, data type, number of non-zero
nodes and sum of the node data values.</p>
<H3>Inputs</H3>
<p><B><I>&in</I></B></p>
<p>Reference to a uniform field with Node_Data of any type. </p>
<H3>Outputs</H3>
<p><B><I>info</I></B></p>
<p>The string containing the description of the field data.</p>
<H3>Utility Macros</H3>
<p>The low-level module nstats_raw is used in the Functional Macro nstats
and the User Macro node_statistics. The latter also uses the UI Macro nstats_UI.</p>
<H3>Example</H3>
<p>An example application Node_Stats_Eg is provided that uses the AVS/Express
sample image mandrill.x to display the node data statistics.</p>
<H3>Files</H3>
<p><I>iac_proj/nstats/ns_mods.v</I> contains the nstats_raw module V definitions.</P>
<P><I>iac_proj/cp_utils</I> contains source code for functions called by
nstats_raw.</p>
<h3>Prerequisites</h3>
<p>
This project relies on the successful installation of
the following components. Without them it will not function
correctly.
</p>
<ul>
<li><a href="../cp_utils/cp_utils.shtml" target="_top">cp_utils</a> project</li>
</ul>
<H3>Other Notes</H3>
<p>By default the low-level library NStatsMods, which needs to be compiled,
has the process set to express.</P>
<P>This module uses functions in the cp_utils library (available from IAC).
It must be installed before compiling this project.</p>
