Function Documentation

void m23d_set_q_constraint1	(	vnl_matrix< double > &	A,
		vnl_vector< double > &	rhs,
		unsigned	c,
		const vnl_vector< double > &	a,
		const vnl_vector< double > &	b,
		double	r
	)

Defines constraint on elements of Q of form a'Qb=r.

Q is a symmetric matrix, with n(n+1)/2 independent elements The constraints on these elements are placed in row c of A

void m23d_set_q_constraint2	(	vnl_matrix< double > &	A,
		vnl_vector< double > &	rhs,
		unsigned	c,
		const vnl_vector< double > &	a,
		const vnl_vector< double > &	b
	)

Defines constraint on elements of Q of form aQa'-bQb'=0.

Q is a symmetric matrix, with n(n+1)/2 independent elements The constraints on these elements are placed in row c of A

void m23d_set_q_constraints	(	const vnl_matrix< double > &	M,
		unsigned	k,
		vnl_matrix< double > &	A,
		vnl_vector< double > &	rhs
	)

Generate matrix of all constraints on elements of Q.

Q symmetric, encoded using elements i,j<=i in the vector q q obtained by solving Aq=rhs
