# xwvd

Cross Wigner-Ville distribution and cross smoothed pseudo Wigner-Ville distribution

## Syntax

## Description

returns the cross smoothed pseudo Wigner-Ville distribution of `d`

= xwvd(___,'smoothedPseudo')`x`

and
`y`

. The function uses the length of the input signals to choose the
lengths of the windows used for time and frequency smoothing. This syntax can include any
combination of input arguments from previous syntaxes.

`xwvd(___)`

with no output arguments plots the real
part of the cross Wigner-Ville or cross smoothed pseudo Wigner-Ville distribution in the
current figure.
