| elastic.depth {fdasrvf} | R Documentation |
This functions calculates the elastic depth between set of functions
elastic.depth(f, time, lambda = 0, parallel = FALSE)
f |
matrix of N function of M time points (MxN) |
time |
sample points of functions |
lambda |
controls amount of warping (default = 0) |
parallel |
run computation in parallel (default = T) |
Returns a list containing
amp |
amplitude depth |
phase |
phase depth |
