How to convert euler angles or quaternion into xy(cartesian)coordinates

[KSSV]

If you have polar coordinates (r,theta), you can convert them to Cartesian using pol2cart. How a angle alone can be converted to Cartesian coordinates?

[James Tursa]

Euler angles and quaternions typically represent rotations, so converting them to xy positions doesn't make sense. Can you give us more detail about what you are trying to do, and why you think you need this conversion?
