Namespaces
namespace	stir
	Namespace for the STIR library (and some/most of its applications)
namespace	stir::BSpline
	Namespace for functions and classes for B-Spline interpolation in the STIR library.

Typedefs
typedef double	stir::BSpline::pos_type
	The type used for relative positions between the grid points.

Enumerations
enum	stir::BSpline::BSplineType {   near_n , linear , quadratic , cubic ,   quartic , quintic , oMoms }
	enum providing constants to define the type of B-Spline used for interpolation

Functions
template<class RandIterOut, class IterT, class constantsT>
void	stir::BSpline::BSplines_coef (RandIterOut c_begin_iterator, RandIterOut c_end_iterator, IterT input_begin_iterator, IterT input_end_iterator, const constantsT z1, const constantsT z2, const constantsT lambda)
	compute BSpline coefficients that gives the BSpline that interpolates the given data
template<typename pos_type>
pos_type	stir::BSpline::BSplines_1st_der_weight (const pos_type relative_position, const BSplineType spline_type)
	return value of the first derivative of the spline
template<typename pos_type>
pos_type	stir::BSpline::BSplines_weights (const pos_type relative_position, const BSplineType spline_type)
	return spline value
