tfg.geometry.transformation.rotation_matrix_2d.from_euler

Converts an angle to a 2d rotation matrix.

tfg.geometry.transformation.rotation_matrix_2d.from_euler(
    angle, name='rotation_matrix_2d_from_euler_angle'
)

Converts an angle

$$\theta$$

to a 2d rotation matrix following the equation

$$ \mathbf{R} = \begin{bmatrix} \cos(\theta) & -\sin(\theta) \\ \sin(\theta) & \cos(\theta) \end{bmatrix}. $$

The resulting matrix rotates points in the

$$xy$$

-plane counterclockwise.

In the following, A1 to An are optional batch dimensions.

Args
`angle`	A tensor of shape `[A1, ..., An, 1]`, where the last dimension represents an angle in radians.
`name`	A name for this op that defaults to "rotation_matrix_2d_from_euler_angle".

Returns
A tensor of shape `[A1, ..., An, 2, 2]`, where the last dimension represents a 2d rotation matrix.

Raises
`ValueError`	If the shape of `angle` is not supported.
