The function atan2d gives angles that are from -180 to 180. Not a problem. This works:
mod(atan2d(y,x),360)
But you want the angles in a CLOCKWISE orientation? You do understand that is not the standard?
mod(360 - atan2d(y,x),360)
I won't ask why you need them in a clockwise orientation. The angles that come from this second expression are angles relative to a horizontal line, and proceeding CLOCKWISE around the origin.
Note that mod still works even if the angles are not integers. For example:
mod(360 - atan2d(-2,1),360)
ans =
63.435
So this points at an angle 63 degrees BELOW the right branch of the x-axis.
