Leigh;
Do you have examples: x y pairs where you can test y = foo D.n x? I
suspect that Roger et al have covered many of the usual suspects:
polynomials, trig functions, even gamma... the J help page for D. seems
to confirm this.

Dear Raul and J Forum:
I was aware of the D. operator, and admire the solution. My only question
is how accurately D. performs numerical differentiation. Can I rely on it,
or should I seek numerical methods for deriving the gamma functions?
Thanks.
Sincerely,
Leigh
