public class GriddedSet extends SampledSet implements GriddedSetIface
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.
Grid coordinates are zero-based and in the range -0.5 to length-0.5 i.e., there are "length" intervals of length 1.0, the first centered on 0.0 and the last centered on length-1.0 points outside this range are indicated by the grid coordinate Double.NaN.
