% Calculate the parallax Computes the parallax of a target when viewed by an observer offset from the origin of the reference frame. -------------------------------------------------------------------------- Form: [u, parallax] = Parallax( rT, rO ) -------------------------------------------------------------------------- ------ Inputs ------ rT (3,1) Position vector of the target rO (3,1) Position vector of the observer ------- Outputs ------- u (3,1) Unit vector to the target parallax (1,1) Parallax (rad) --------------------------------------------------------------------------
Math: Linear/Unit
