Hi,

#include There are a few root finding algorithm in the above file. I'm not sure if there is the false-position method in there?

What I want is give an interval which only has one root. I want to always find the root in that interval. I'm wondering if any function in that header can do so or not.

To be more specific, I'm wondering if toms748_solve does this?

Yes, but it's considerably more complex internally (and more efficient) than the classic false position method since it combines bisection with secant, cubic and quadratic interpolation. Indeed for certain classes of problems it's the most efficient method possible without derivative information. HTH, John.
