Class rootsolvers.Solvers 

java.lang.Object
   |
   +----rootsolvers.Solvers
public class Solvers
extends Object
This class is intended to contain a variety of root-solving algorithms, each with possibly distinct interfaces. The function to be solved is made available through the Solved interface with its calcf)OfX method. Hence, each algorithm method will take as a first argument a Solved object. Done in this manner, these algorithm methods can all be static. It is also sensible to have the algorithm methods return the root as a double. The rest of the arguments may vary with the algorithm. Use of this class and the Solved interface is demonstrated in the SolversTest application. This approach to using an interface closely follows the examples in Core Java 1.1, Volume 1 by Horstmann & Cornell.

o bisection(Solved, double, double)
If one can bracket the root, the bisection algorithm can be used and will find one root with virtual certainty.

Methods

o bisection 
 public static double bisection(Solved s,
                                double x1,
                                double x2) throws RootSolverException
If one can bracket the root, the bisection algorithm can be used and will find one root with virtual certainty. For more information, see W. H. Press, B. P. Flannery, S. A. Teukolsky and W. T. Vetterling, Numerical Recipes (Cambridge Univ., New York, 1988).

Parameters:
s - Solved object containing the function to be solved
x1 - one bound on the range of the root
x2 - other bound
Returns:
root of the function
Throws: RootSolverException
thrown when a root isn't found
