I am currently trying to use cuFFT lib to do a up sampling process, the process is like:
- do a FFT to get a fft result say: 1111111111
- then put them in a bigger array : 000000000011111111110000000000
- then do a iFFT to get a up sampled result.
But it looks like cuFFT handles data differently I can’t get the results I needed, I am suspecting that in the case of cuFFT, I should not put data in the bigger array like I did in the 2 step, do you guys have any idea how should I handle the data in the second step?
