A Vector is a 3x1 matrix containing X-Y-Z coordinate values. It is used for representing: 3D position of a point wrt a reference frame, rotational and translational part of a 6D motion or force entity : <equation id="vector"><equation>

Creating Vectors

<equation>
Creating Rotations
Safe ways to create a Rotation
The following result always in consistent Rotations. This means the rows/columns are always normalized and orthogonal:
<equation>
Creating Frames
  f1==f2;  f1!=f2;  Equal(f1,f2,eps);
