Hi guys,

Are convolution algorithm or fast Fourier transform implemented to perform filtering or frequency analysis?

It could be of great interest.

Kind Regards,

Luis

Hi @lnicalo ,

These aren't currently implemented, but I'd like to add them at some point.

Hi, Has FFT algorithm been implemented? If yes, kindly share the library which should be used for the same.

Thanks & Regards, Sumitra
