Document

Algorithm Description: scales the output of Random.nextDouble(), but rejects 0 values (i.e., will generate another random double if Random.nextDouble() returns 0).

Usage

From source file:datafu.pig.hash.lsh.p_stable.AbstractStableDistributionFunction.java

public void reset(int dim, double w) throws MathException {
    RandomDataImpl dataSampler = new RandomDataImpl(rg);
    Sampler sampler = getSampler();/* w ww . j  a v a  2s.  c om*/
    this.a = new double[dim];
    this.dim = dim;
    this.w = w;
    for (int i = 0; i < dim; ++i) {
        a[i] = sampler.sample(dataSampler);
    }
    b = dataSampler.nextUniform(0, w);
}
