You can just go onto your console, and run
fftwf-wisdom --measure 1024
assuming 1024 is your FFT length, and it will do the same thing as it
does when you construct a 1024-FFT in GNU Radio, i.e. go ahead and try
out its different algorithms, and find the best one for that FFT
length, and then p
So according to the link the library doesn't utilize one particular algorithm
but is optimized to use the "best" algorithm depending on n according to this
link
https://cnx.org/contents/ulXtQbN7@15/Implementing-FFTs-in-Practice
So, is there any particular way to figure out which algorithm is us
GNU Radio uses the FFTW library.

Scroll down to the "Literature" section for detailed papers.
