Uses FFT and returns amplitudes and phases of the Fourier components.

Syntax:
S = FSA(X,INTERVAL,OUTPUT,OPT)

Inputs:
X Series
INTERVAL Data sampling interval (hour)
OUTPUT Print(fid or filename)/show results [ {1} 0 <filename> ]
OPT Permissions of fopen [ 'w' ]

Output:
S Structure with result: .f .T .amp .pha (frequency, period, amplitude and phase)

The screenshot shows the period vs amplitude for one series with two components with amplitudes 1, 2, phases 30, 80 and periods 12, 24
