Member Function Documentation

template<int dim>
virtual double Functions::Bessel1< dim >::value ( const Point< dim > &  p,
const unsigned int  component 
) const
virtual

Return the value of the function at the given point. Unless there is only one component (i.e. the function is scalar), you should state the component you want to have evaluated; it defaults to zero, i.e. the first component.

Reimplemented from Function< dim >.

template<int dim>
virtual void Functions::Bessel1< dim >::value_list ( const std::vector< Point< dim > > &  points,
std::vector< double > &  values,
const unsigned int  component = 0 
) const
virtual

Set values to the point values of the specified component of the function at the points. It is assumed that values already has the right size, i.e. the same size as the points array.

By default, this function repeatedly calls value() for each point separately, to fill the output array.

Reimplemented from Function< dim >.

template<int dim>
virtual Tensor<1,dim> Functions::Bessel1< dim >::gradient ( const Point< dim > &  p,
const unsigned int  component = 0 
) const
virtual

Return the gradient of the specified component of the function at the given point.

Reimplemented from Function< dim >.

template<int dim>
virtual void Functions::Bessel1< dim >::gradient_list ( const std::vector< Point< dim > > &  points,
std::vector< Tensor< 1, dim > > &  gradients,
const unsigned int  component = 0 
) const
virtual

Set gradients to the gradients of the specified component of the function at the points. It is assumed that gradients already has the right size, i.e. the same size as the points array.

Reimplemented from Function< dim >.
