ClassDescriptionImplements a bell-shaped switching function by stitching together a pair of MultiplicativeSwitches.The CompositeSwitch uses a primary switch in the middle, and then two secondary switches at the ends of the path to smoothly switch to the primary switch.The ConstantSwitch returns a constant value for all input values x.A LinearDerivativeSwitch interpolates between 0 and 1 vi f(x) = 2*x - x^2.The 6 coefficients of the multiplicative polynomial switch are unique given the distances "a" and "b".A PowerSwitch interpolates between 0 and 1 vi f(x) = (ax)^beta, where x must be between 0 and 1/a.A SquaredTrigSwitch implements a 0-1 switch of form f(x) = sin^2(ax) or of form f(x) = cos^2(ax).Static class responsible for parsing String arrays into univariate switching functions.A UnivariateSwitchingFunction describes a function of a single value (often lambda), where f(lb) = 0, f(ub) = 1, and df(x)/dx >= 0 for all x lb-ub.
