int getOrder() const
Order of this shapelet expansion.
double getRadius() const
Return the radius of this shapelet expansion.
ndarray::Array< double const, 2, 2 > getMatrix() const
Matrix whose elements [i,j] map MultiShapeletBasis elements j to shapelet terms i.
void merge(MultiShapeletBasis const &other)
Combine the given basis with this (in place), by appending its elements.
void normalize()
Rescale all matrices so each element has unit flux.
int getComponentCount() const
Return the number of components (distinct shapelet bases) in the MultiShapeletBasis.
int getSize() const
Return the number of elements (i.e. free amplitudes) in the MultiShapeletBasis.
void scale(double factor)
Multiply the radius of all basis elements by the given factor.
MultiShapeletFunction makeFunction(afw::geom::ellipses::Ellipse const &ellipse, ndarray::Array< double const, 1, 1 > const &coefficients) const
Create a MultiShapeletFunction from the basis.
void addComponent(double radius, int order, ndarray::Array< double const, 2, 2 > const &matrix)
Add a new component (shapelet basis) to the MultiShapeletBasis.
