Class IndicesRange

java.lang.Object
org.jblas.ranges.IndicesRange
All Implemented Interfaces:
Range
public class IndicesRange extends Object implements Range
Range which varies over pre-specified indices. For example,

    Range r = new IndicesRange(indices);
ranges over the first few Fibonacci numbers.
