warp.time {ptw}

Transform time according to a given warping function

Description

Warp time points according to a warping function.

Usage

warp.time(tp, coef)

Arguments

tp

A vector of time points, not necessarily equidistant.

coef

The coefficients of the parametric time warping function: the first coefficient is the constant shift, the second the linear stretch etcetera.

Value

The function returns a vector of warped time points.
