Examples of org.jblas.ranges.Range

org.jblas.ranges.Range
The Range interface represents basically a set of indices. Before using a range you have to call init() with the actually available lower and upper bounds, such that you can also have an "AllRange" which contains all possible indices.

Further operations include:
- length() - returns total number of elements.
- next() - increase counter (use value()) to retrieve the value.
- index() - get the index of the current value.
- value() - get the current value.
- hasMore() - more indices available.
Typical uses look like this:
```
    for (r.init(lower, upper); r.hasMore(); r.next()) { System.out.printf("Value number %d is %d%n", index(), value()); }
```

    SimpleBlas.sygvx(1, 'V', 'V', 'U', A.dup(), B.dup(), vl, vu, 0, 0, abstol, m, W, Z);
    if (m[0] == 0) {
      throw new NoEigenResultException("No eigenvalues found for selected range");
    }
    DoubleMatrix[] result = new DoubleMatrix[2];
    Range r = new IntervalRange(0, m[0]);
    result[0] = Z.get(new IntervalRange(0, A.rows), r);
    result[1] = W.get(r, 0);
    return result;
  }
