# scaleSpectrum

## Syntax

## Description

`[`

also returns the scale indices over which the scale-averaged wavelet spectrum is computed.
If you do not specify `savgp`

,`scidx`

] = scaleSpectrum(___)`FrequencyLimits`

or
`PeriodLimits`

, `scidx`

is a vector from 1 to the
number of scales.

`[___] = scaleSpectrum(___,`

specifies additional options using name-value pair arguments. These arguments can be added
to any of the previous input syntaxes. For example,
`Name,Value`

)`'Normalization','none'`

specifies no normalization of the
scale-averaged wavelet spectrum.

`scaleSpectrum(___)`

with no output arguments plots the
scale-averaged wavelet power spectrum in the current figure.
