Utilizes cubature (integration) rules contained in the library Polylib (Spencer Sherwin,...
Scalar beta_
Jacobi parameter beta.
int dimension_
Dimension of integration domain.
void getAccuracy(std::vector< int > &accuracy) const
Returns max. degree of polynomials that are integrated exactly. The return vector has size 1.
EIntrepidPLPoly poly_type_

int getNumPoints() const
Returns the number of cubature points.
const char * getName() const
Returns cubature name.
void getCubature(ArrayPoint &cubPoints, ArrayWeight &cubWeights) const
Returns cubature points and weights (return arrays must be pre-sized/pre-allocated).
Scalar alpha_
Jacobi parameter alpha.
static const char * cubature_name_
Cubature name.
virtual int getDimension() const
Returns dimension of integration domain.
int degree_
The degree of polynomials that are integrated exactly by this cubature rule.
Defines the base class for cubature (integration) rules in Intrepid.
