Class HessianBFGS_DDRM

java.lang.Object
org.ddogleg.optimization.math.HessianMath_DDRM

All Implemented Interfaces:
HessianBFGS, HessianMath

public class HessianBFGS_DDRM
extends HessianMath_DDRM
implements HessianBFGS
Uses DFP to estimate the Hessian and BFGS to estimate the inverse Hessian. See [1]. A more efficient way to do this would be to compute the Cholesky decomposition directly, then use that for forward and inverse operations
