can I use it? If yes, How?
Are you trying to use octave's fftconv2 function? In Fedora35 with octave
and octave-image installed using dnf:
octave:8> pkg load image
pkg load image
octave:9> help fftconv2
'fftconv2' is a function from the file
-- Function File: fftconv2 (A, B)
-- Function File: fftconv2 (V1, V2, A)
-- Function File: fftconv2 (..., SHAPE)
Convolve 2 dimensional signals using the FFT.
This method is faster but less accurate than CONV2 for large A and
B. It also uses more memory. A small complex component will be
introduced even if both A and B are real.
See also: conv2, fftconv, fft, ifft.
