Pretty cool, thanks for releasing this into the wild.  I remember
looking into this about a year ago.  By the way, have you seen Matt's
DSP library?

http://haskelldsp.sourceforge.net/

He's got LU and others in there, if my memory serves me.  The last
release seems to be 2003, so it might be worth emailing him to see
what happened and if he has plans for the future.

Regards,

Paulo
