numpy.fft.rfft(a, n=None, axis=-1, norm=None)[source] -
Compute the one-dimensional discrete Fourier Transform for real input.
This function computes the one-dimensional n-point discrete Fourier Transform (DFT) of a real-valued array by means of an efficient algorithm called the Fast Fourier Transform (FFT).
Parameters: a : array_like
Input array
n : int, optional
Number of points along transformatio
