Just FYI for all of you Numerical Recipes fans, this announcement
appeared in Wavelet Digest:

> From: Bill Press, Harvard University.
> Date: Tue, 21 Jul 92 11:40:31 -0400
> Subject: Numerical Recipes software 
>
> This fall, the second edition of the Numerical Recipes book will come

> and C.

Now a question: has anyone compiled a list of replacement routines
for those found in NR? By replacement routines, I mean net sources
(anonymous ftp) that can be redistributed with PD software. Would
such a list be legal if it included the names of corresponding
NR routines? Would it be legal/ethical to redistribute such a list?
(I have the humble beginnings of a list.)

Email unless you feel this discussion is appropriate on 
sci.math.num-analysis.

Of course it's legal and ethically appropriate to work on
such a list.  I'm incredibly irritated at NR for not making their
code open (like Linpack, say).

To the extent that the code has appeared in print, it's hard for them
to sue anyone; you can't prove in court of law that I did not type out
the code from the book.  Functions like dmatrix() are the only real
catch.  I have a full (and superior) reimplementation of these.
Send me email for more info; they will appear by ftp "soon".

        -ans.
