Wilson-Daubechies-Mayer wavelet transform.

wdmwavelet.rwdm(x, nt, nf, trans_width, steepness, axis=-1)

Compute WDM transform for real input.

Parameters:

• x (array_like) – Input array.

• nt (int) – N_t.

• nf (int) – N_f.

• trans_width (float) – Width of transition interval.

• steepness (float) – Steepness of transition interval.

• axis (int) – Axis to be transformed.

Returns:

w – WDM coefficients, stored in the last two axes.

Return type:

np.ndarray

wdmwavelet.irwdm(w, trans_width, steepness)

Compute the inverse of real WDM transform rwdm.

Parameters:

• w (array_like) – Input WDM coefficients, stored in the last two axis.

• trans_width (float) – Width of transition interval.

• steepness (float) – Steepness of transition interval.

• axis (int)

Returns:

Inverse of w.

Return type:

np.ndarray
