Wigner-Ville distribution and smoothed pseudo Wigner-Ville distribution

specifies additional options for the smoothed pseudo Wigner-Ville distribution using
name-value pair arguments. You can specify `d`

= wvd(___,'smoothedPseudo',`Name,Value`

)`twin`

and
`fwin`

in this syntax, or you can omit them.

`wvd(___)`

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