Hi,
Supposed I'm given linear velocity and center of rotation in 3D. Can I obtain the angular velocity? I tried using: v = w x r v (1x3 vector) = A (3x3 matrix) * w (1x3 vector) then take the inverse of the 3x3 matrix A and w = inv A * v But the inverse of A gave an error. Why is this so? Are there other ways? I have the linear velocity and xyz coordinates of its location. Thanks. |
