Method Summary

Modifier and Type	Method and Description
default double	apply(double x) Computes the value of the function at x.
double	f(double x) Computes the value of the function at x.

Method Detail

f

double f(double x)

Computes the value of the function at x.

apply

default double apply(double x)

Computes the value of the function at x. It delegates the computation to f(). This is simply for Scala convenience.
