LinearFunction

data class LinearFunction(val slope: Double, val intercept: Double = 0.0, val domain: Range<Double> = Range.all()) : UnivariateFunction

Linear function of the form f(x) = slope * x + intercept.

Parameters

slope

slope of linear function

intercept

intercept at f(0)

domain

defined domain for the function
