smooth3

I am using smooth3 "BOX smoothing method" in order to smooth my data. I need to know how it does the filtering. I know that it makes some averaging over given number of neighbors, however I need to know its detail mathematical principle and formula including the assumptions taken for the boundary regions. Thank you so much in advance!

Well from opening smooth3

open smooth3

and taking a quick look at the code, it looks like the kernel for a box is:

smooth = ones(sz)/prod(sz);
