Typedefs
typedef afw::geom::ellipses::Quadrupole	lsst::shapelet::EllipseCore
typedef ndarray::Array< double, 1 >	lsst::shapelet::Array1d
	Typedef for a commonly-used array type.

Enumerations
enum	lsst::shapelet::BasisTypeEnum { lsst::shapelet::HERMITE , lsst::shapelet::LAGUERRE }
	An enum that sets whether to use real-valued polar shapelets or Cartesian shapelets. More...

Functions
int	lsst::shapelet::computeOffset (int order)
	Return the offset of the given order in a coefficient vector.
int	lsst::shapelet::computeSize (int order)
	Return the size of the coefficient vector for the given order.
int	lsst::shapelet::computeOrder (int size)
	Infer the order of a shapelet expansion from the number of coefficients.
double	lsst::shapelet::intSqrt (int n)
	Compute the square root of an integer number.
double	lsst::shapelet::rationalSqrt (int n, int d)
	Compute the square root of a rational number i.e. sqrt(n/d)

Variables
double const	lsst::shapelet::BASIS_NORMALIZATION
	Normalization factor for 1-d orthonormal shapelets: pi^(-1/4)
