Examples of org.jblas.ranges.IntervalRange

org.jblas.ranges.IntervalRange
Range which varies from a given interval. Endpoint is exclusive!
"new IntervalRange(0, 3)" enumerates 0, 1, 2.

    DoubleMatrix Z = new DoubleMatrix(A.rows, A.rows);
    SimpleBlas.sygvx(1, 'N', '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");
    }
    return W.get(new IntervalRange(0, m[0]), 0);
