Class ErfcWeight

  • All Implemented Interfaces:
    WeightFunction

    public final class ErfcWeight
    extends java.lang.Object
    implements WeightFunction
    Gaussian Error Function Weight function, scaled such that the result it 0.1 when the distance is the maximum using: \( \text{erfc}(1.1630871536766736 \frac{\text{distance}}{\max}) \).

    The value of 1.1630871536766736 is erfcinv(0.1), to achieve the intended scaling.

    Since:
    0.2

        getWeight in interface WeightFunction
        Parameters:
        distance - distance of the query point
        max - maximum distance of all included points
        stddev - standard deviation (i.e. quadratic mean / RMS) of the included points
        Returns:
        weight for the query point
