Hy all, i want to show my image behind the figure like the below image, let say my image 128x128 pixel, so i have 4x4 squares and i get the arrow (representation of the gradient magnitude and orientation)
But, i just got something like this
I didn't know how to show the gridlines and the arrows.
Any little help is important to me, thanks.

If the grid is not to go edge to edge then you will need to draw it yourself.
If it is to go edge to edge, then grid on

You can use line() to graw grid lines. You can use quiver() or annotation() to draw arrows.

quiver can create the arrows. plot() or line() or surf() or patch() to create the green lines. The same set of functions or viscircles or rectangle to create the circle .
