The program estimates the largest Lyapunov exponent of a given scalar data set using the algorithm of Rosenstein et al.

Everything not being a valid option will be interpreted as a potential datafile name. Given no datafile at all, means read stdin. Also - means stdin

Possible options are:

Option | Description | Default |
---|---|---|

-l# | number of data to be used | whole file |

-x# | number of lines to be ignored | 0 |

-c# | column to be read | 1 |

-m# | embedding dimension to use | 2 |

-d# | delay to use | 1 |

-t# | window around the reference point which should be omitted | 0 |

-r# | minimal length scale for the neighborhood search | (data interval)/1000 |

-s# | number of iterations in time | 50 |

-o# | output file name | 'datafile'.ros (or stdin.ros if data was read from stdin) |

-V# | verbosity level 0: only panic messages 1: add input/output messages 2: add statistics for each iteration | 3 |

-h | show these options | none |

**First column:**Number of the iteration**Second column:**Logarithm of the stretching factor
