Function Documentation

Solution G4INCL::RootFinder::solve	(	RootFunctor const *const	f,
		const G4double	x0
	)

Numerically solve a one-dimensional equation.

Numerically solves the equation f(x)==0. This implementation uses the false-position method.

If a root is found, it can be retrieved using the getSolution() method,

Parameters

f	pointer to a RootFunctor
x0	initial value of the function argument

Returns

a Solution object describing the root, if it was found
