# bandpower

Band power

## Syntax

## Description

returns the average power computed by integrating the power spectral density
(PSD) estimate `p`

= bandpower(`pxx`

,`f`

,"psd")`pxx`

. The integral is approximated by the
rectangle method. The input `f`

is a vector of frequencies
corresponding to the PSD estimates in `pxx`

. The
`"psd"`

option indicates that the input is a PSD estimate
and not time series data.

returns the average power contained in the frequency interval
`p`

= bandpower(`pxx`

,`f`

,`freqrange`

,"psd")`freqrange`

. If the frequencies in
`freqrange`

do not match values in
`f`

, the closest values are used. The average power is
computed by integrating the power spectral density (PSD) estimate
`pxx`

. The integral is approximated by the rectangle
method. The `"psd"`

option indicates the input is a PSD
estimate and not time series data.
