ext: 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.
