idwtmat(mmix_wt, n_coefs_approx)[source]

Invert wavelet transform data with order 2 Daubechies wavelet.

Parameters:
  • 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.
Returns:

mmix_iwt – Inverse wavelet-transformed data.

Return type:

{S, T} numpy.ndarray
