The extra parameters can be any legal octave value, the new fsolve
simply works by storing all the arguments after the independent variable
then passing them to foo separately. I have only tried it with scalars,
but I can't see a reason matrices won't work. I actually only had to add
about 10 lines to fsolve. Let me know it it has problems.
