Warping Smoothness

Computes the bending energy of a warping function, measuring its roughness.

Usage

warp.smoothness(gamma, argvals)

Arguments

gamma

Numeric vector of warping function values.

argvals

Numeric vector of grid points.

Value

A scalar smoothness (bending energy) value.

Examples

t <- seq(0, 1, length.out = 20)
warp.smoothness(t^2, t)
#> [1] 4
