rotation3d_xΒΆ
Rotation matrix about the x axis by the input angle \(\Phi\)
\[\begin{split}\mathbf{\tau}_x = \begin{bmatrix}
1 & 0 & 0 \\
0 & \cos(\Phi) & -\sin(\Phi) \\
0 & \sin(\Phi) & \cos(\Phi)
\end{bmatrix}\end{split}\]
param angle: | angle of rotation in radians about the x axis |
---|---|
type angle: | float |
returns: | 3x3 rotation matrix about the x axis |
rtype: | np.array |
