ext: Extrema of Dyadic Wavelet Transform

In Rwave: Time-Frequency Analysis of 1-D Signals

Extrema of Dyadic Wavelet Transform

Description

Compute the local extrema of the dyadic wavelet transform modulus.

Usage

ext(wt, scale=FALSE, plot=TRUE)

Arguments

wt	dyadic wavelet transform.
scale	flag indicating if the extrema at each resolution will be plotted at the same scale.
plot	if set to TRUE, displays the transform on the graphics device.

Value

Structure containing:

original	original signal.
extrema	extrema representation.
Sf	coarse resolution of signal.
maxresoln	number of decomposition scales.
np	size of signal.
