public class IrregularSet

extends SampledSet

IrregularSet is implemented by those Set sub-classes whose samples do not form any ordered pattern. It is a M-dimensional array of points in R^N where ManifoldDimension = M <= N = DomainDimension.

The order of the samples is the rasterization of the orders of the 1D components, with the first component increasing fastest. For more detail, see the example in Linear2DSet.java.
