Hi Ondrej,
As requested I have attached a modification and a test case. The modification checks a value for equality to zero, but maybe it should more appropriately handle values near zero. Also, other functions in nonlin.py may benefit from similar modifications.
Excellent, thanks a lot for the work. Here are my comments:
denominator = norm(deltaFxm)**2 if not denominator: break
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
use -> us
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".
use -> us. O.
