List of all members.

Detailed Description

template<class DT, class RT, int n, int m>
class Dune::HdivFunction< DT, RT, n, m >

Abstract base class for Hdiv functions.

The divergence can be taken. But as an L2 function its pointwise values might not be unique

Template parameters are:

DT type for components of the input vector
RT type for the return values
n dimension of the input space
m number of components of the vector-valued function

template<class DT, class RT, int n, int m>

virtual int Dune::HdivFunction< DT, RT, n, m >::order ( ) const [inline, virtual]

returns order 1

For Hdiv functions we can implement it here.

Implements Dune::DifferentiableFunction< DT, RT, n, m >.

template<class DT, class RT, int n, int m>

virtual RT Dune::DifferentiableFunction< DT, RT, n, m >::derivative	(	int	comp,
		const Dune::FieldVector< int, n > &	d,
		const Dune::FieldVector< DT, n > &	x
	)			const `[pure virtual, inherited]`

evaluate partial derivative

Evaluate partial derivative of a component of the vector-valued function.

Parameters:

`[in]`	comp	number of component that should be differentiated
`[in]`	d	vector giving order of derivative for each variable
`[in]`	x	position where derivative is to be evaluated

Returns:: value of the derivative

evaluate single component comp at global point x

Evaluate a single component of the vector-valued function.

Parameters:

`[in]`	comp	number of component to be evaluated
`[in]`	x	position to be evaluated

Returns:: value of the component
