Each embedded point is replaced by theaverage vector calculated in its neighbourhood with a given size. Thisis different from what is described in <ahref="../chaospaper/citation.html#lazy">Schreiber</a>. There and inthe program <a href="../docs_f/lazy.html">lazy</a> only the centralcomponent of each vector is corrected. It is advisable to give both atry. We found a tendency that <a href="../docs_f/lazy.html">lazy</a>performs better on map like data while <font color=blue>nrlazy</font>is superiour on flow like data.<hr><h2 align=center>Usage:</h2><center><font color=Red>nrlazy [Options]</font><p>Everything not being a valid option will be interpreted as a potentialdatafile name.

If the verbosity level is set accordingly, the secondcolumn contains the number of neighbors found for this point. If thisnumber is 1, no correction is done at all for this point.<hr>View the <a href="../../source_c/nrlazy.c"> C-sources</a>.<hr>See also <a href="../docs_f/lazy.html">lazy</a> <hr><a href=../contents.html>Table of Contents</a> * <a href="../../index.html" target="_top">TISEAN home</a></body></html>⌨️ 快捷键说明
