Excellent, thanks a lot for the work. Here are my comments:
denominator = norm(deltaFxm)**2
if not denominator:
use abs(denominator) < eps
and define eps as a default parameter of the function, for example eps=1e-10.
Also could you please apply this into the scipy svn, and send use the
output of "svn di"? So that someone with a svn access can just take it
and apply it.
As to the tests, please add them to
scipy/optimize/tests/test_nonlin.py. Simply do all of this in your
local svn copy and send use the result of "svn di".
Thanks very much,
