fsolve and fsolve_options

[Heber Farnsworth]

I have two questions that don't seem well documented.  First, what sort of
algorithm is fsolve using?  I read that it comes from hybrid in MINPACK but I'm
not familiar with that.  I'm finding that it's giving me different answers than
one that I wrote (mine is better it seems) and I want to know why?

Second what are the options that can be adjusted with fsolve_options?  I know
that tolerance can be changes but I can't tell what others may or may not be.
