fft
(xi, yi, axis=0) → tuple[source]¶ Take the 1D FFT of an N-dimensional array and return “sensible” properly shifted arrays.
- Parameters
xi (numpy.ndarray) – 1D array over which the points to be FFT’ed are defined
yi (numpy.ndarray) – ND array with values to FFT
axis (int) – axis of yi to perform FFT over
- Returns
xi (1D numpy.ndarray) – 1D array. Conjugate to input xi. Example: if input xi is in the time domain, output xi is in frequency domain.
yi (ND numpy.ndarray) – FFT. Has the same shape as the input array (yi).
