Namespaces
namespace	BTK
namespace	BTK::MATH
Typedefs
Vector and Matrix types.
The BTK* types are typedefs to appropriate classes in the Boost::ublas linear algebra library. Using these types in the BTK makes it easier to write/read linear algebra code, and easier to switch the code to other linear algebra systems (should that ever become necessary).
typedef uBLAS::symmetric_matrix< double >	BTKSymmetricMatrix
Functions
bool	within_sqr_dist (BTKVector const &a, BTKVector const &b, double r_squared)
	See if two vectors are within a squared distance threshold of one another.
double	point_angle (BTKVector const &v1, BTKVector const &v2, BTKVector const &v3)
	calculate the angle formed by v1-v2 amd v3-v2
double	point_dihedral (BTKVector const &a, BTKVector const &b, BTKVector const &c, BTKVector const &d)
	Calculate the dihedral angle between the planes a-b-c and d-c-b.
BTKVector	set_vector_from_dihedral (BTKVector const &v3, BTKVector const &v2, BTKVector const &v1, double len34, double ang234, double dih1234)
	calculate vector position from a dihedral angle
BTKVector	set_vector_from_two_angles (BTKVector const &v3, BTKVector const &v2, BTKVector const &v1, double len34, double ang234, double ang134)
	Calculate vector position from two vector angles.
