Extrema of Dyadic Wavelet Transform
.DN
Compute the local extrema of the dyadic wavelet transform modulus.
.CS
ext(wt, scale=FALSE, plot=TRUE)
.RA
.AG wt
dyadic wavelet transform.
.OA
.AG scale
flag indicating if the extrema at each 
resolution will be plotted at the same scale.
.AG plot
if set to T, displays the transform on the graphics device.
.RT
Structure containing:

original:original signal.

extrema:extrema representation.

Sf:coarse resolution of signal.

maxresoln:number of decomposition scales.

np:size of signal.
