Detailed Description

template<int dim>
class Functions::CutOffFunctionLinfty< dim >

Cut-off function in L-infinity for an arbitrary ball. This function is the characteristic function of a ball around center with a specified radius, that is,

\[ f = \chi(B_r(c)). \]

If vector valued, it can be restricted to a single component.

Constructor & Destructor Documentation

template<int dim>
Functions::CutOffFunctionLinfty< dim >::CutOffFunctionLinfty ( const double  radius = 1.,
const Point< dim >  = Point< dim >(),
const unsigned int  n_components = 1,
const unsigned int  select = CutOffFunctionBase< dim >::no_component 
)

Constructor. Arguments are the center of the ball and its radius.

If an argument select is given and not -1, the cut-off function will be non-zero for this component only.
