Member Function Documentation

void HessMatrix::MultV	(	UserVector< double > &	y,
		const UserVector< double > &	x
	)			const [inline, virtual]

Computes the product of the Hessian and a UserVector<double>.

Parameters:

	y	The UserVector<double> to store the result in: .
	x	The UserVector<double> to multiply with the Hessian.

See also:

Func::HessMult(dvector&, const dvector&, const dvector&)

Implements UserMatrix.
