Estimated timeline

Most of my discussion is based on my wiki post in which I delve into details how I want to approach the problem. This post is available here. I am aware that it might change as I go along but for now I do not have any new information which could help me estimate how much time each task takes.

Taking under consideration the aforementioned wiki page I estimate that I will do as follow:
  1. For the next couple of weeks (May 6-17) I will try to test the Octave functions and compare them to the ones from the TISEAN package. Also I intend to do other tasks to facilitate my work later (e.g. fix the makefile)
  2. Next I will start porting according to the schedule outlined in the wiki. I would like to finish and clean up 'Dimensions and Entropies' before the midterm assessment.
  3. In the following 4 weeks or so I would like to finish the project up, obviously this might not be possible and that is why I leave myself a time 'cushion' if my estimates are mistaken.
The biggest problem I foresee in the 1st stage is that FORTRAN programs use floats and Octave uses double, so the results might be different. This is a problem, especially in cases when data relies on some previously calculated data. I have tried different numbers and so far I saw that for 'henon' the difference between the result has been < 10^-3 (or <10^-2 later on) so I assumed they are the same. As of writing this I do not know how to elegantly compare the two data sets so as to compensate for the difference that results from floats and doubles.
