This page describes the progress on porting the TISEAN package into an Octave Package. This project was started as part of the Google Summer of Code 2015.
To aid in understanding the task there are some charts.
The first chart depicts what to do with each function in the function table. I mainly focuses on those functions that might already implemented in Octave.
The chart below depicts how to decide which type of port should be utilized.
Both of those charts can be combined into a large one that shows all of the work together.
