Member Function Documentation

cost()

int OMDc::LineSearchFunctor::cost	(	Eigen::VectorXd &	fvec,
		const Eigen::MatrixXd &	L
	)		const

evaluates cost function at bases

Parameters

fvec	cost function value (scalar-valued)
L	bases where geodesic is evaluated

Returns

0 for success

costDim()

const Eigen::Index OMDc::LineSearchFunctor::costDim ( )

inline

dimension of the cost function vector

Returns

dim == 1

derivative()

double OMDc::LineSearchFunctor::derivative	(	Eigen::MatrixXd &	dF,
		const Eigen::MatrixXd &	L
	)		const

componentwise derivative w.r.t. given modes

Parameters

dF	reference to derivative (n x r)
L	given modes (n x r)

Returns

value of the cost function
