Matrix: Help with syntax and comparison with SparseM
Hi,
I am writing some basic smoothers in R for cleaning some spectral data.
I wanted to see if I could get close to matlab for speed, so I was
trying to compare SparseM
with Matrix to see which could do the choleski decomposition the
fastest.
Here is the function using SparseM
difsm <- function(y, lambda, d){
# Smoothing with a finite difference penalty
# y: signal to be smoothed
#
