rot_about_y¶
- lsst.ts.mthexapod.rot_about_y(xyzpos: ndarray[Any, dtype[float64]], ang: float) ndarray[Any, dtype[float64]]¶
Rotate a 3-d position about the y axis.
Positive rotation is from from z to x (the usual right-hand rule).
- Parameters:
- xyzpos
numpy.ndarray x, y, z position.
- ang
float Angle in radians.
- xyzpos
- Returns:
- rotpos
numpy.ndarray Rotated x,y,z position.
- rotpos
