# modwpt

Maximal overlap discrete wavelet packet transform

## Syntax

## Description

returns the
terminal nodes for the maximal overlap discrete wavelet packet transform
(MODWPT) for the 1-D signal, `wpt`

= modwpt(`x`

)`x`

. The output is time-delayed
compared to the input signal. For more information, see MODWPT and MODWPT Details.

`[`

returns a vector of transform
levels corresponding to the rows of `wpt`

,`packetlevs`

]
= modwpt(___)`wpt`

.

`[`

returns the center frequencies
of the approximate passbands corresponding to the rows of `wpt`

,`packetlevs`

,`cfreq`

]
= modwpt(___)`wpt`

.

`[`

returns the energy (squared L`wpt`

,`packetlevs`

,`cfreq`

,`energy`

]
= modwpt(___)^{2}-norm)
of the wavelet packet coefficients for the nodes in
`wpt`

.

`[___] = modwpt(___,`

specifies options using one or more name-value arguments in addition to the
input arguments in previous syntaxes. For example, to return the full wavelet
packet tree, set `Name=Value`

)`FullTree`

to
`true`

.
