pyrfu.pyrf.wavelet module#
- pyrfu.pyrf.wavelet.wavelet(inp, **kwargs)[source]#
Computes wavelet spectrogram based on fast FFT algorithm. :param inp: Input quantity. :type inp: xarray.DataArray :param **kwargs:
- Hash table of keyword arguments with :
- fsint or float
Sampling frequency of the input time series.
- flist or ndarray
Vector [f_min f_max], calculate spectra between frequencies f_min and f_max.
- nfint or float
Number of frequency bins.
- wavelet_widthint or float
Width of the Morlet wavelet. Default 5.36.
- linearfloat
Linear spacing between frequencies of df.
- return_powerbool
Set to True to return the power, False for complex wavelet transform. Default True.
- cut_edgebool
Set to True to set points affected by edge effects to NaN, False to keep edge affect points. Default True
- Returns:
out – Wavelet transform of the input.
- Return type:
