This function does not compute the negative frequency terms, and the length of the transformed - axis of the output is therefore ``n//2+1``. + axis of the output is therefore ``n//2 + 1``. When ``A = rfft(a)`` and fs is the sampling frequency, ``A[0]`` contains the zero-frequency term 0*fs, which is real due to Hermitian symmetry. |
