I am sorry if what follows is a simple question. I haven't thought about
it that much, I have to admit. Is there a way to evaluate the error fcn.
at some (possibly complex) point z? The error function, you may recall,
is defined as
erf(z) = {2\over \sqrt{\pi}} \int_{0}^z e^{-t^{2}}dt
using standard (Plain) TeX syntax. Of course, I can evaluate it using
Mathematica, but since I have to do so many times within a Monte Carlo
simulation program, I would like to able to evaluate it using Ox direc-
tly, if possible.
Thanks in advance. Regards,
Francisco
