Amplitude Distance Matrix — amplitude.distance • fdars

Compute the pairwise amplitude distance matrix. The amplitude distance is the elastic (Fisher-Rao) distance after optimal alignment.

Usage

amplitude.distance(fdataobj, fdataref = NULL, lambda = 0, ...)

Arguments

fdataobj: An object of class 'fdata'.
fdataref: Optional reference 'fdata'. If NULL, computes self-distances.
lambda: Penalty weight. Default 0.
...: Additional arguments (ignored).

Value

A distance matrix.

Examples

# \donttest{
fd <- fdata(matrix(rnorm(60), 6, 10), argvals = seq(0, 1, length.out = 10))
D <- amplitude.distance(fd)
# }
