rot_about_z

lsst.ts.mthexapod.rot_about_z(xyzpos: tuple[float, float, float], ang: float) → ndarray[Any, dtype[float64]]

Rotate a 3-d position about the z axis.

Positive rotation is from x to y (the usual right-hand rule).

Parameters:

xyzpostuple [float]

x, y, z position.

angfloat

Angle in radians.

Returns:

rotposnumpy.ndarray

Rotated x,y,z position.
