Whole spectrum means: If dcomponents are given and the embeddingdimension is m than m*d exponents will be determined. The method isbased on the work of <a href="../chaospaper/citation.html#sasa">Sano and Sawada</a>.<hr><h2 align=center>Usage:</h2><center><font color=Red>lyap_spec [Options]</font><p>Everything not being a valid option will be interpreted as a potential datafile name.
