I have gotten many responses from people who are interested
in getting the code for the PV wave/matlab interface, so I
thought I would update folks in this group on its status.
First, for those of you who didn't see the original posting,
here is a description of what the interface does and my
current status as to trying to get it released (this is copied
from a note I just sent to somebody who inquired about the
interface):

> 3) you can use pv wave's plotting paramters to create more
> complex plots (titles, tick marks, colors, etc)
> 4) you can get post script output of your plots from matlab (this feature
> alone is worth all the trouble it took to write the interface).
> The real advantage, though, to using the interface is that you can create
