ifft

PURPOSE ^

IFFT - ifft transforms a HFRC object

SYNOPSIS ^

function h = ifft( h, all, varargin )

DESCRIPTION ^

 IFFT - ifft transforms a HFRC object

 Usage: res = ifft( hfrc_obj, ifft_all, ... )

 res will depend on ifft_all.  If ifft_all is 0, then only U and V will be
 ifft transformed and an HFRC object will be returned with
 temporal_domain='frequencyUV'.  If ifft_all is 1, then all relevant
 variables in hfrc_obj will be ifft transformed and an HFRC object will
 be returned with temporal_domain='frequencyALL'.

 If ifft_all is a string, then the string will be treated as the name of a
 variable in hfrc_obj and the inverse Fourier transform of that variable
 will be returned.

 ... are other arguments to be passed to ifft directly.

 ifft is much quicker if the number of elements in the series is a
 multiple of 2.  I suggest dropping the last element before applying ifft
 if this is not the case.
