I am studying about Information Technoloy at HCMUS. Through 3 years, I never see that prototype of this function.
static void FUNCTION(fft_halfcomplex,pass_4) (const BASE in, const size_t istride, BASE out, const size_t ostride, const size_t product, const size_t n, const TYPE(gsl_complex) twiddle1, const TYPE(gsl_complex) twiddle2, const TYPE(gsl_complex) twiddle3)
Could You explain what the central part of this prototype (FUNCTION(fft_halfcomplex,pass_4)) is to me?
I am sure that this code can run well. If you do not belive me, you can download this at http://www.fon.hum.uva.nl/praat/download_sources.html and you will see.
