dwtmat
(mmix)[source]¶ Wavelet transform data using order 2 Daubechies wavelet.
Parameters: mmix ({S, T} numpy.ndarray
) – Data to wavelet transform.Returns: - mmix_wt ({S, 2C}
numpy.ndarray
) – Wavelet-transformed data. Approximation and detail coefficients are horizontally concatenated for each row in mmix. - n_coefs_approx (
int
) – The number of approximation coefficients from the wavelet transformation. Used to split the wavelet-transformed data into approximation and detail coefficients.
