Hi Matthew,
I've been working on "rolling/windowed" libraries for quite a while.
I'm currently working on implementations for basic moment and rank
statistics - they are pretty much done and I am trying to maneuver them
into apache commons math for java.
I am also interested in implementing the
Hi all,
I'm not sure if my terminology is familiar but I'm trying to do a
"moving window" analysis (ie a spatial filter or kernel) on a 2-D
array representing elevation. For example, a 3x3 window centered on
each cell is used to calculate the derivate slope of that cell.
Can this easily be impl
