warp_srvf: Applies a warping function to a given SRVF

In fdasrvf: Elastic Functional Data Analysis

Applies a warping function to a given SRVF

Description

Applies a warping function to a given SRVF

Usage

warp_srvf(qfun, gamfun, betafun = NULL)

Arguments

qfun	A function that takes a numeric vector s of values in [0, 1] as input and returns the values of the SRVF of an underlying curve at s.
gamfun	A function that takes a numeric vector s of values in [0, 1] as input and returns the values of a diffeomorphic warping function at s.
betafun	A function that takes a numeric vector s of values in [0, 1] as input and returns the values of the underlying curve at s. Defaults to NULL.

Value

A function that takes a numeric vector s of values in [0, 1] as input and returns the values of the warped SRVF.

Examples

q <- curve2srvf(beta[, , 1, 1])
warp_srvf(q, get_identity_warping())
