AbstractLinAlgPack::value_type AbstractLinAlgPack::sum ( const Vector & v_rhs )

result = sum( v_rhs(i), i = 1,,,dim )

AbstractLinAlgPack::value_type AbstractLinAlgPack::dot	(	const Vector &	v_rhs1,
		const Vector &	v_rhs2
	)

result = v_rhs1' * v_rhs2

AbstractLinAlgPack::value_type AbstractLinAlgPack::dot	(	const Vector &	v_rhs1,
		const SpVectorSlice &	sv_rhs2
	)

result = v_rhs1' * sv_rhs2

AbstractLinAlgPack::value_type AbstractLinAlgPack::dot	(	const SpVectorSlice &	sv_rhs1,
		const Vector &	v_rhs2
	)

result = sv_rhs1' * v_rhs2

void AbstractLinAlgPack::max_abs_ele	(	const Vector &	v,
		value_type *	max_v_j,
		index_type *	max_j
	)

Compute the maximum element in a vector.

Parameters

v	[in] The vector being searched
max_v_j	[out] The value of the element with the max abs value.
max_j	[out] The index of the element with the max abs value.

Returns:

max_v_j = v(max_j) s.t. |v(max_j)| <= |v(j)|, for j = 1...n

If there is a tie, the lowest index is returned so that the result is unique no matter what order the vector elements are searched.
