This version differs from the simple one in providing an extra argument to the sampling action that will be globally distributed to every node and can be used to update the state. For instance, it
can hold the time step between the two samplings, but it could also encode all the external input to the system.

Linear Transformation to Block-wise Stack Matrix
As I wrote in my original post, for a (1 x 2) input, the elegant solution is to simply use the matrix transpose. However, it is not clear how to generalise this for larger block structures (e.g. a
solution that perhaps involves both matrix multiplications and transposes)... | {"url":"http://www.physicsforums.com/showthread.php?t=513905","timestamp":"2014-04-19T15:09:01Z","content_type":null,"content_length":"58094","record_id":"<urn:uuid:7d538297-98d5-42db-aa03-1a753cc88624>","cc-path":"CC-MAIN-2014-15/segments/1398223206120.9/warc/CC-MAIN-20140423032006-00299-ip-10-147-4-33.ec2.internal.wa... |

Ordinary Kriging
The first step in ordinary kriging is to construct a variogram from the scatter point set to be interpolated. A variogram consists of two parts: an experimental variogram and a model variogram.
