Parameters ---------- data: array_like Input data wavelet : Wavelet object or name string Wavelet to use level : int, optional Decomposition level (must be >= 0). If level is None (default) then it will be calculated using the `dwt_max_level` function. axis: int, optional Axis over which to compute the DWT. If not given, the last axis is used.

The decomposition using ``transform='dwt'`` corresponds to section 2.2 while that using an undecimated transform (``transform='swt'``) is described in section 3.2 and appendix A. This transform does not share the variance partition property of ``swt`` with `norm=True`. It does however, result in coefficients that are temporally aligned regardless of the symmetry of the wavelet used. The redundancy of this transform is ``(level + 1)``. References ---------- ..
