Class LineSampler

    • Method Detail

      • sample

        public double[] sample()
        Description copied from interface: ObjectSampler
        Create a sample.
        Specified by:
        sample in interface ObjectSampler<double[]>
        a random Cartesian coordinate on the line.
      • createSample

        protected abstract double[] createSample​(double p1mu,
                                                 double u)
        Creates the sample given the random variate u in the interval [0, 1]. The sum 1 - u is provided. The sample can be obtained from the line ab using:
         p = a(1 - u) + ub
        p1mu - plus 1 minus u (1 - u)
        u - the variate u

                                     double[] b)
        Create a line sampler with vertices a and b. Sampled points are uniformly distributed on the line segment ab.

        Sampling is supported in dimensions of 1 or above.

        rng - Source of randomness.
        a - The first vertex.
        b - The second vertex.

        IllegalArgumentException - If the vertices do not have the same dimension; the dimension is less than 1; or vertices have non-finite coordinates.
