	I've been trying to write an extremum finder in C for a
while now, with no success.  The routine accepts initial values
for an array of coefficients and a pointer to a function, and
searches for the nearest local minimum using a gradient search
on the coefficients.  Seems simple, right?  Well, no.  I've been
having all sorts of problems, and I don't know what to do.  If
any of you have written something similar, please let me know.
(Esp. if you have an extremeum finder that finds the *absolute*
minimum/maximum!)
