WaveletMapIndexed

WaveletMapIndexed[f, wd] applies the function f to the arrays of coefficients and indices of a ContinuousWaveletData or DiscreteWaveletData object.

• WaveletMapIndexed[f, dwd, wind] applies f to the DiscreteWaveletData coefficients specified by wind.
• WaveletMapIndexed[f, cwd, octvoc] applies f to the ContinuousWaveletData coefficients specified by octvoc.

Examples

dwd = DiscreteWaveletTransform[{1, 2, 3, 4, 5, 6, 7, 8}];
WaveletMapIndexed[Abs, dwd]

WaveletMapIndexed[# * 2 &, dwd, {1}]
