Paul Riseborough e9ccfdd484 EKF: Update derivation scripts and outputs
Work around limitation in Symbolic toolbox environment space by incrementally saving and clearing workspace
Remove vehicle vertical position from optical flow prediction equations (use range measurement instead) and regenerate auto-code
Remove legacy optical flow auto-code conversion method as it is not required now a work around for symbolic toolbox limitations has been developed
Fix out of date syntax
