Class UnivariateRealSolverFactory

java.lang.Object
  extended by org.apache.commons.math.analysis.UnivariateRealSolverFactory
Direct Known Subclasses:
UnivariateRealSolverFactoryImpl

public abstract class UnivariateRealSolverFactory
extends Object

Abstract factory class used to create UnivariateRealSolver instances.

Solvers implementing the following algorithms are supported:

Concrete factories extending this class also specify a default solver, instances of which are returned by newDefaultSolver().

Common usage:

 SolverFactory factory = UnivariateRealSolverFactory.newInstance();

 // create a Brent solver to use with a UnivariateRealFunction f
 BrentSolver solver = factory.newBrentSolver(f);
 
Jakarta Commons Discovery is used to determine the concrete factory returned by UnivariateRealSolverFactory.newInstance(). The default is UnivariateRealSolverFactoryImpl.
