ext {Rwave} | R Documentation

## 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.
