void Example()
{
    Vector vec1(0);
        // first, generate 1000 randomly Rayleigh distributed
        // numbers with b=1.3
        vec1.Size(1000,false);
        RandomRayleigh(1.3,vec1,-1);
    // Now extract the r and it's 95% confidence intervals.
    double resb;
    DewArray<double> CIb(2);
    RayleighFit(vec1,resb,CIb,0.05);
