Purpose & Params

Rotate a coordinate on the y-axis given a euler rotation matrix.

Example

    # Rotates the coordinate v 90 degrees on the y-axis
    v = np.array([1,0,0])
    radian_y        = 0.5 * np.pi
    rotation_matrix = mat3.Ry(radian_y)
    print(np.dot(rotation_matrix, v))

output:

   [ 6.123234e-17  0.000000e+00 -1.000000e+00]
