I want to make outputs (which must contain the line along with arrow head) in X-Z plane; i.e. view([180 0]), not in 3D which is good for visualization only. Unfortunately, though the line is visible, the arrow head is not seen when I go into 2D view. I tried to include 'CrossDir',[0 0 1] as suggested by the author of the script, but it didn't help. Any suggestion?
Gridfit is very nice. I have written an update that adds bicubic interpolation and improves the internal scaling (makes surface smoothness completely independent of the x/y grid size). If I send you the code, would you update Gridfit?
Alejandro - while I would like to implement that capability one day in the future, that day may be a long time away before I find the time. Until then, all I can offer is to use a finer grid, which will mimic a higher order interpolant.
