I have a 2D array input buffer. so, what is the correct way to implement the rfft and cfft functions?
float fftIn[16][512] is my input. So, I applied for a loop like below:
arm_rfft_fast_init_f32(&fftHandler, 512);
Solved! Go to Solution.

For those of you who might need help with 2D FFT, this is the correct approach.

Can anyone explain this?

No help directly, but the first (or second) rule of algorithm development and testing is to have a known input data and the expected output, preferably multiple sets of inputs and outputs. Without that you are just wasting your time.
