DiscreteWaveletTransform

DiscreteWaveletTransform[data] gives the discrete wavelet transform (DWT) of an array of data.

DiscreteWaveletTransform[data, wave] gives the DWT using the wavelet wave.

DiscreteWaveletTransform[data, wave, r] gives the DWT using r levels of refinement.

Examples

Basic wavelet transform:

DiscreteWaveletTransform[{1, 2, 3, 4, 5, 6, 7, 8}]

With Daubechies wavelet:

DiscreteWaveletTransform[Range[16], DaubechiesWavelet[4]]
