pysteps.utils.spectral.std¶
- pysteps.utils.spectral.std(X, shape, use_full_fft=False)¶
Compute the standard deviation of a two-dimensional array in the spectral domain.
- Parameters
- X: array_like
A complex array representing the Fourier transform of a two-dimensional array.
- shape: tuple
A two-element tuple specifying the shape of the original input array in the spatial domain.
- use_full_fft: bool
If True, X represents the full FFT of the original array. Otherwise, it is assumed to contain only the symmetric part, i.e. in the format returned by numpy.fft.rfft2.
- Returns
- out: float
The standard deviation.
