◆ 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
levelThe level where the index is considered
numPointsThe number of points at the level
indexThe index of the concrete point in the level

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.
