[SciPy-Dev] Chirp Z-transform

Hi all,

is this implmentation related to the new ICZT algorithm?
(https://www.nature.com/articles/s41598-019-50234-9)

This is absolutely fascinating stuff, but there also seems to be a
patent on the algorithm:

Maybe that's no problem at all (I haven't researched what the licensing
terms are), but it might need careful checking.

Cheers,
  Martin
