dis.cos.cor: Proximities between functional data

Description

Computes the cosine correlation distance between two functional dataset of class fdata.

Usage

dis.cos.cor(fdata1, fdata2 = NULL, as.dis = FALSE)

Value

Returns a proximity/distance matrix (depending on as.dis) between functional data.

Arguments

fdata1

Functional data 1 or curve 1.

fdata2

Functional data 2 or curve 2.

as.dis

Returns the distance matrix como 1-cor(fdata1,fdata2).
