computeRotationMatrix()

def lsst.skymap.detail.dodecahedron.computeRotationMatrix	(		angle,
			axis
	)

Return a 3D rotation matrix for rotation by a specified amount around a
specified axis.

Parameters
----------
angle : `float`
    Amount of rotation (rad).
axis : `int`
    Axis of rotation; one of 0, 1 or 2 for x, y or z.
