Hi all, I know this question was answered sometime last year, but I can't figure out how to use 2D FFT.
What I currently have *//4x4 array. Every i is real, every i+1 is imag ** //This array is 16, because 4x4, and *2, because we have to store real and imag* *double *a = new double[16*2]; gsl_fft_complex_radix2_forward(a, 1, 16); * Now as far as I know, to solve 2D FFT, I must first do a column-based FFT and then a row-based FFT (according to last years post). How exactly will I do this, is there another function in GSL? Thanks for any help!! _______________________________________________ Help-gsl mailing list Help-gsl@gnu.org https://lists.gnu.org/mailman/listinfo/help-gsl
