virtual int getNumPoints() const
Returns the number of cubature points.
Header file for the Intrepid::CubatureDirectLineGauss class.
virtual void getCubature(ArrayPoint &cubPoints, ArrayWeight &cubWeights) const
Returns cubature points and weights (return arrays must be pre-sized/pre-allocated).
virtual void getAccuracy(std::vector< int > &accuracy) const
Returns algebraic accuracy (e.g. max. degree of polynomial that is integrated exactly).
Definition file for the Intrepid::CubatureGenSparse class.
Defines the base class for cubature (integration) rules in Intrepid.
virtual int getDimension() const
Returns dimension of the integration domain.
Header file for the Intrepid::Cubature class.
