Hello, thank you very much for this solution, i'll try to adapt it to my problem, i think i'll be able to. By the way, i wrote about a "sliding-window" weight matrix, it's an expression used in satellite images processing, esp. convolution filters, meaning that the main matrix is not confronted to another one of the same dimensions, but to a much smaller one. The calculus is executed value by value (pixels on an image), centering the small matrix on each one, hence the name of sliding window.
