Class FactoryOptimizationSparse

java.lang.Object

org.ddogleg.optimization.FactoryOptimizationSparse

public class FactoryOptimizationSparse
extends Object

Factory for sparse optimization algorithms. These implementations/interfaces are designed to be easy to use and effective for most tasks. If more control is needed then create an implementation directly.
