</h1>
<hr>
The program estimates the largest Lyapunov exponent of a given scalar
data set using the algorithm of <a

<font color=Red>lyap_r [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

Possible options are:
