Are Numerical Recipes any good yet? I haven't looked for about a
decade, but the last time I had correspondence with Bill Press he
couldn't understand that the fundamental mathematical foundation of
MEDFIT (an L1 fitting routine) was flawed: It depended on derivatives
exactly and only where they don't exist! Then he couldn't understand
that it was a Bad Thing that the (flawed) mathematics was converted into
an algorithm incorrectly, or that the (inherently incorrect) algorithm
was coded incorrectly. Lots of other areas were defective. Have they
been repaired?
