Class PlusMult

  • All Implemented Interfaces:
    DoubleDoubleFunction


    public final class PlusMultextends Objectimplements DoubleDoubleFunction
    Only for performance tuning of compute intensive linear algebraic computations. Constructs functions that return one of
    • a + b*constant
    • a - b*constant
    • a + b/constant
    • a - b/constant
    a and b are variables, constant is fixed, but for performance reasons publicly accessible. Intended to be passed to matrix.assign(otherMatrix,function) methods.

      • multiplicator

        public double multiplicator
        Public read/write access to avoid frequent object construction.
    • Method Detail

      • apply

        public final double apply(double a,           double b)
        Returns the result of the function evaluation.
        Specified by:
        apply in interface DoubleDoubleFunction
        Parameters:
        a - the first argument passed to the function.
        b - the second argument passed to the function.
        Returns:
        the result of the function.
