astroforge.coordinates.Rz

astroforge.coordinates.Rz(angle)

Create a rotation matrix about the third axis by the given rotation angle. The rotation matrix is given by:

\[\begin{split}\begin{bmatrix} \cos (\theta) & \sin (\theta) & 0.0 \\ -\sin (\theta) & \cos (\theta) & 0.0 \\ 0.0 & 0.0 & 1.0 \end{bmatrix}\end{split}\]

Parameters:

angle (float) – Rotation angle (radians)

Returns:

R – Rotation matrix

Return type:

NDArray[np.float64]
