Detailed Description

Agglomeration class for various useful polynomial routines.

Function Documentation

brentRootFinder()

RealVect PolyUtils::brentRootFinder	(	const RefCountedPtr< BaseIF > &	a_impFunc,
		const RealVect &	a_point1,
		const RealVect &	a_point2
	)

Compute the root of a function between two points. This is a 1D problem along the line.

Parameters

[in]	a_impFunc	Implicit function
[in]	a_point1	First end-point
[in]	a_point2	Other end-point

Note

The root MUST be bracketed, i.e. f(x1)*f(x2) < 0.0. Anything else is an error.
