Re: fttconv2

Yes, exactly.

Actually the package 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.

Hello,

octave-image provide fftconv2.m

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

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.

 

     See also: conv2, fftconv, fft, ifft.
