Detailed Description
template<typename ct, int dim>
class Dune::QuadraturePoint< ct, dim >
class Dune::QuadraturePoint< ct, dim >
Single evaluation point in a quadrature rule.
A quadrature point is a single (position, weight)
pair used to evaluate a function at a position with a relative weight.
- Template Parameters
-
ct Number type used for both coordinates and the weights dim Dimension of the integration domain

Tuple like accessor for contents of a quadrature point.
This function is used by the compiler to generate structured binding for the (position, weight) pair. Thus, the snippet
QuadraturePoint<double,2> quad_point = ...;
const Vector & position() const
return local coordinates of integration point i
Definition: quadraturerules.hh:82
const ct & weight() const
return weight associated with integration point i
Definition: quadraturerules.hh:88
is equivalent to
QuadraturePoint<double,2> quad_point = ...;
- Template Parameters
-
index Positional argument of the quadrature point contents
- Returns
- Position (
index==0
) or weight (index==1
).
