Functions

func Cubic

func Cubic(y0, y1, y2, y3, fractionalDistance float64) float64

Cubic performs 4-point, 3rd-order (cubic) Hermite interpolation (x-form). Given 4 evenly-spaced sample points and a fractional distance (0 to 1), interpolates a value between the middle two points. Source: https://www.musicdsp.org/en/latest/Other/93-hermite-interpollation.html

func Linear

func Linear(y0, y1, fractionalDistance float64) float64

Linear performs linear interpolation between two points. Given y-values from two points and a fractional distance (0 to 1), calculates the y-value for a point between them.
