[Scilab-users] Moving window over 2D grid

[Rafael Guerra]

Hi Lester,

Without further information, the simplest approach would be to write two nested loops.

Now, regarding the computation of radially averaged PSDs, you may want to take a look in the web for published code.
For example, look at the function raPsd2d, written by Ruzanski (2009) for Matlab.

Rafael
