Detailed Description

Function Documentation

void AbstractLinAlgPack::Vp_S	(	VectorMutable *	v_lhs,
		const value_type &	alpha
	)

v_lhs += alpha

Definition at line 166 of file AbstractLinAlgPack_VectorStdOps.cpp.

void AbstractLinAlgPack::Vt_S	(	VectorMutable *	v_lhs,
		const value_type &	alpha
	)

v_lhs *= alpha

This takes care of the special cases of alpha == 0.0 (set v_lhs = 0.0) and alpha == 1.0 (don't do anything).

void AbstractLinAlgPack::Vp_StV	(	VectorMutable *	v_lhs,
		const value_type &	alpha,
		const Vector &	v_rhs
	)

v_lhs = alpha * v_rhs + v_lhs

Definition at line 191 of file AbstractLinAlgPack_VectorStdOps.cpp.

void AbstractLinAlgPack::Vp_StV	(	VectorMutable *	v_lhs,
		const value_type &	alpha,
		const SpVectorSlice &	sv_rhs
	)

v_lhs = alpha * sv_rhs + v_lhs

Definition at line 203 of file AbstractLinAlgPack_VectorStdOps.cpp.

void AbstractLinAlgPack::ele_wise_prod	(	const value_type &	alpha,
		const Vector &	v_rhs1,
		const Vector &	v_rhs2,
		VectorMutable *	v_lhs
	)

v_lhs(i) += alpha * v_rhs1(i) * v_rhs2(i), i = 1,,,dim.

void AbstractLinAlgPack::ele_wise_divide	(	const value_type &	alpha,
		const Vector &	v_rhs1,
		const Vector &	v_rhs2,
		VectorMutable *	v_lhs
	)

v_lhs(i) = alpha * v_rhs1(i) / v_rhs2(i), i = 1,,,dim.

void AbstractLinAlgPack::seed_random_vector_generator

(

unsigned int

s

)

Seed the random number generator.

Definition at line 242 of file AbstractLinAlgPack_VectorStdOps.cpp.

void AbstractLinAlgPack::random_vector	(	value_type	l,
		value_type	u,
		VectorMutable *	v
	)

Generate a random vector with elements uniformly distrubuted elements.

The elements are randomly generated between [l,u].

Definition at line 247 of file AbstractLinAlgPack_VectorStdOps.cpp.

void AbstractLinAlgPack::sign	(	const Vector &	v,
		VectorMutable *	z
	)

Compute the sign of each element in an input vector.

        / -1.0 : if v(i)  < 0.0
z(i) =  |  0.0 : if v(i) == 0.0
        \ +1.0 : if v(i)  < 0.0

, for i = 1...n
