how to use NAFF in matlab AT

[simoneliuzzo]

Which commands should be used in matlab AT to use NAFF algorithm to assess tunes from turn-by-turn data?

Hello @simoneliuzzo , for matlab I cannot comment but I remember there were issues with the license.
Alternatively there is the module harmonic_analysis.py of pyAT that implements a same algorithm as NAFF (method=laskar) to determine the tune

Dear @swhite2401 ,

thank you for your reply. I would need the matlab version as the code I am running is written in matlab.

Hello Simone,
there is the function calcnaff, written by @lnadolski.

Hi all,

Historically, NAFF was method 4 in findtunes.m. At some point, it was removed, I don't know why. The git history is not deep enough to find the original version, but I think it should be restored.

A search for nafflib (the mex function) in the entire project shows only calcnaff, so for the time being Nicola is right, it's the only access.
