sffft3 (3.0)
index
system/generic/Mfft3.c
FFT transform on extra axis.

 
Synopsis
        sffft3 < in.rsf > out.rsf inv=n sym=n sign=inv? 1: 0 opt=y axis=2 pad=2

Input and output are complex data. The input is padded by factor pad.

Parameters
       
 
int axis=2
Axis to transform
 
bool inv=n [y/n]
if y, perform inverse transform
 
bool opt=y [y/n]
if y, determine optimal size for efficiency
 
int pad=2
padding factor
 
int sign=inv? 1: 0
transform sign (0 or 1)
 
bool sym=n [y/n]
if y, apply symmetric scaling to make the FFT operator Hermitian
