[SciPy-user] Finding all the roots in an interval
Mon Oct 1 01:48:32 CDT 2007
I can't help but to jump in with an old and probably obscure
reference to a paper
BUSH JONES, W. G. WALLER and ARNOLD FELDMAN,
"Root isolation using function values"
(Google the title)
which gives a rather neat solution to this problem.
No, it is not foolproof, but it would be successful
for the problem you have stated. Not Python, but Fortran
