Select and initialize a wavelet.
Unit
SignalUtils
Declaration
Procedure WaveletInit(DataLength: integer; Parameter1, Parameter2, Level: integer; WaveletType: TWaveletType; var State: TWaveletState);
Description
Initialize wavelet State variable. DataLength defines the number of samples on which to perform wavelet decomposition. Parameter1 and Parameter2 are parameters for some wavelets types defined with WaveletType. Complex signals are not supported. Wavelet decomposition/reconstruction is initialized with depth Level. The result of the decomposition on each level are detail and approximation. Approximation is placed in the first half of the array and the detail in second half. Approximation is recursively further decomposed on each level.
