Hi
I have a vector defined by P1. [12,14,78]
How can I caculate the angle this forms with the xy, xz an yz planes pls.
I can do with atan(x/y) etc, but this is problematic when the angle is over 90 or 180.
What would be the best approach pls

From your graph it looks to me the angles are between vector P and basis vectors and not the planes

P1=[12,14,78]
xyzc=num2cell(eye(3),1)
[x,y,z]=deal(xyzc{:});
rad2deg(subspace(P1(:),[x y]))
rad2deg(subspace(P1(:),[x z]))
rad2deg(subspace(P1(:),[y z]))
