Dyadic Wavelet Transform

Dyadic wavelet transform, with Mallat's wavelet. The reconstructed signal preserves locations and values at extrema.

Keywords
ts
Usage
mw(inputdata, maxresoln, filtername="Gaussian1", scale=FALSE, plot=TRUE)
Arguments
inputdata

either a text file or an R object containing data.

maxresoln

number of decomposition scales.

filtername

name of filter (either Gaussian1 for Mallat and Zhong's wavelet or Haar wavelet).

scale

when set, the wavelet transform at each scale is plotted with the same scale.

plot

indicate if the wavelet transform at each scale will be plotted.

Details

The decomposition goes from resolution 1 to the given maximum resolution.

Value

Structure containing

original

original signal.

Wf

dyadic wavelet transform of signal.

Sf

multiresolution of signal.

maxresoln

number of decomposition scales.

np

size of signal.
