org.jblas.ranges.RangeUtils

public class RangeUtils
extends Object

A bunch of static functions for making construction of ranges more uniform. Basically, we have

• point(3) - a PointRange.
• indices(new int[] {1,2,3,...}) - a Indices Range.
• interval(1, 2) - an interval range.
• all() - an AllRange.
• indices(x) - with a DoubleMatrix.
• find(x) - an index constructed from the non-zero elements of x.
