Invert a Warping Function

Compute the functional inverse of a warping function \(\gamma\), i.e., find \(\gamma^{-1}\) such that \(\gamma(\gamma^{-1}(t)) = t\).

Usage

warp.inverse(gamma, argvals)

Arguments

gamma

Numeric vector of warping function values.

argvals

Numeric vector of evaluation points.

Value

Numeric vector of the inverse warping function.

Examples

t <- seq(0, 1, length.out = 50)
gamma <- t^2
gamma_inv <- warp.inverse(gamma, t)
