Compute the local extrema of the dyadic wavelet transform modulus.
ext(wt, scale=FALSE, plot=TRUE)
dyadic wavelet transform.
flag indicating if the extrema at each resolution will be plotted at the same scale.
if set to TRUE, displays the transform on the graphics device.
Structure containing:
original signal.
extrema representation.
coarse resolution of signal.
number of decomposition scales.
size of signal.
