Re: spectral rotation algorithm; please ignore

Dear list

This is very strange, but my message from several weeks ago seems to have been re-sent to the list for somee reason. I can assure you I didn't do it as I was not even at my desk for the last two days. Anyway, just to say that I don't know why this message was sent around again, but please ignore it. I already received help from several people concerning the spectral rotation issue.

Subject: spectral rotation algorithm
Dear List

Does someone have handy a matlab script that will perform spectral 
rotation? We are looking for something that will simply take a signal 
and flip it around a given frequency. There are probably several ways to 
do this, but if anyone has a ready-made script that would save us a bit 
of time.

Thanking you in advance
