Class UnivariateRealSolverFactory

java.lang.Object
  org.apache.commons.math.analysis.solvers.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:

• Bisection
• Brent's method
• Secant method

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
 BrentSolver solver = factory.newBrentSolver();
