Hi Rafael, I reviewed the methodology applied in GMT (grdfft) and they use tapering from the grid edges to zero. The documentation page details more:
GMT_grdfft <http://gmt.soest.hawaii.edu/doc/5.4.4/grdfft.html> The padding method that has been discussed previously is the similar to that of grdfft edge-point symmetry, but without the tapering to zero. It would be handy to have this padding and tapering better defined in Scilab for 2D grids.
