sffft3
index
filt/proc/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
