Class LinSpace

java.lang.Object

math.coord.LinSpace

public final class LinSpace
extends Object

Evenly spaced points between start and end. The spacing between the points is (end-start)/(n-1) where n is the number of points. A LinSpace always includes the endpoints. If end is smaller than start, then the LinSpace describes descending values.

Note that indexes are 1-based!
