extraction of harmonic terms from FFT in idl
hi all, I am working on a time series vegetation index image which has 23 bands that record vegetation phenology of a year. How can I extract the harmonic terms from FFT in IDL if I run the code on this image hypercube? since I am new in IDL, I can't understand it properly. with thanks, Prasenjit
