Hello, I get the following error: error: feval: function 'fftconv2' not found octave-image provide fftconv2.m can I use it? If yes, How?

Yes, exactly. Actually the package * FFTConvolution <https://github.com/jeremyfix/FFTConvolution> call fftconv2 (* https://github.com/jeremyfix/FFTConvolution) In convolution_benchmark.cc feval ("fftconv2", functionArguments, 1); but, I get error: feval: function 'fftconv2' not found I do not know how to call the octave function from a c++ program. It is because a library si not linked?

The author of the package (jeremy.fix) did not answer to my request.

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 help fftconv2 'fftconv2' is a function from the file /usr/share/octave/packages/image-2.12.0/fftconv2.m -- 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.
