Fast Computation of the Uniform Metric for Sets of Functional Data
Returns the matrix of C (uniform) distances between two sets of functional data.
Cmetric(A, B)
A |
Functions of the first set, represented by a matrix of their functional values of
size |
B |
Functions of the second set, represented by a matrix of their functional values of
size |
For two sets of functional data of sizes m and n
represented by matrices of their functional values,
this function returns the symmetric matrix of size m*n whose entry in the
i-th row and j-th column is the approximated C (uniform) distance of the
i-th function from the first set, and the j-th function from the second set.
This function is utilized in the computation of the h-mode depth.
A symmetric matrix of the distances of the functions of size m*n.
