Class Mult

  • All Implemented Interfaces:
    DoubleFunction

    public final class Mult
    extends java.lang.Object
    implements DoubleFunction
    Only for performance tuning of compute intensive linear algebraic computations. Constructs functions that return one of
    • a * constant
    • a / constant
    a is variable, constant is fixed, but for performance reasons publicly accessible. Intended to be passed to matrix.assign(function) methods.
