<h1 align=center>Description of the program: <font color=Blue>nrlazy
</font>
</h1>
<hr>
This program performs <a href="../chaospaper/node23.html" tppabs="http://www.mpipks-dresden.mpg.de/~tisean/TISEAN_2.0/docs/chaospaper/node23.html">simple nonlinear noise reduction</a>. Each embedded point is
replaced by the average vector calculated in its neighbourhood with a
given size. This is different from what is described in <a
href="../chaospaper/citation.html#lazy" tppabs="http://www.mpipks-dresden.mpg.de/~tisean/TISEAN_2.0/docs/chaospaper/citation.html#lazy">Schreiber</a>. There and in the program <a
href="../wuppertal/lazy.html" tppabs="http://www.mpipks-dresden.mpg.de/~tisean/TISEAN_2.0/docs/wuppertal/lazy.html">lazy</a> only the central
component of each vector is corrected. It is advisable to give both a try.
We found a tendency that <a
href="../wuppertal/lazy.html" tppabs="http://www.mpipks-dresden.mpg.de/~tisean/TISEAN_2.0/docs/wuppertal/lazy.html">lazy</a> performs better on map like data while
<font color=blue>nrlazy</font> is superiour on flow like data.

<h2 align=center>Usage:</h2>
<center>
<font color=Red>nrlazy [Options]</font>
<p>
Everything not being a valid option will be interpreted as a potential datafile name. Given no datafile at all, means read stdin. Also <font color=Red>-</font> means stdin
<p>
Possible options are:
<p>
<table border=2>
<tr>
<th>Option
<th>Description
<th>Default
</tr>
<tr>
<th>-l#
<td>number of points to use
<td>whole file
</tr>
<tr>

(or stdin.laz.n if data were read from stdin)<br>

Each of the files produced consists of one column being the filtered
time series.
