WaveletMatrixPlot

WaveletMatrixPlot[dwd] plots the basis tree of wavelet matrix coefficients in the DiscreteWaveletData dwd.

• WaveletMatrixPlot[dwd, r] plots coefficients up to refinement level r.
• WaveletMatrixPlot[dwd, r, func] applies func to coefficients before plotting.

Examples

Create a wavelet matrix plot:

data = Table[Sin[20 t] + Cos[5 t], {t, 0, 1, 0.001}];
dwd = DiscreteWaveletTransform[data];
WaveletMatrixPlot[dwd]

Plot up to a specific refinement level:

WaveletMatrixPlot[dwd, 3]

Apply absolute value before plotting:

WaveletMatrixPlot[dwd, All, Abs]
