Proximities between functional data
Computes the cosine correlation distance between two functional dataset of
class fdata
.
dis.cos.cor(fdata1, fdata2 = NULL, as.dis = FALSE)
fdata1 |
Functional data 1 or curve 1. |
fdata2 |
Functional data 2 or curve 2. |
as.dis |
Returns the distance matrix from class |
Returns a proximities matrix between functional data.
