convertIndex()

size_t sgpp::combigrid::ExponentialChebyshevPointOrdering::convertIndex ( size_t  level, size_t  numPoints, size_t  index  )

virtual

Converts a level-independent index into a corresponding level-dependent index in for the PointDistribution.

Parameters

level	The level where the index is considered
numPoints	The number of points at the level
index	The index of the concrete point in the level

Implements sgpp::combigrid::AbstractPointOrdering.

getSortedPermutationIterator()

std::shared_ptr< AbstractPermutationIterator > sgpp::combigrid::ExponentialChebyshevPointOrdering::getSortedPermutationIterator ( size_t  level, std::vector< double > const &  points, size_t  numPoints  )

virtual

Returns a permutation iterator which first returns the level-independent index of the leftmost point, then the level-independent index of the second-leftmost point, etc.

Implements sgpp::combigrid::AbstractPointOrdering.

numPoints()

size_t sgpp::combigrid::ExponentialChebyshevPointOrdering::numPoints ( size_t  level )

virtual

Returns the number of points in the given level.

Implements sgpp::combigrid::AbstractPointOrdering.
