TISEAN is not maintained anymore, So inheriting bugs is just not good.
If TISEAN gets into Octave Forge I will take over maintenance with the
help of whoever is actively developing for it.
Also, I expect that in the long run TISEAN will eventually dissolve
into control, signal and tsa.

I will continue with the proposed methodology.

Juan,

I have tried to looked for functions in octave that correspond to the TISEAN programs. The results of my research I have put into a table that is accessible at the following link:

http://wiki.octave.org/User:Josiah425:TISEAN_Package:Table_of_functions

Would you like to comment on it?

Should I incorporate it to my "Elaborated proposal page" ?

:)
