I am working in LINGO software. I have two matrices X and Y with different sizes. I need to write all the elements of the two matrices in one unit vector Z. Did any one encountered such a case before and was able to do it?

    $\begingroup$ Oh, that makes more sense. I'll leave it to someone else to answer then. $\endgroup$ – Billy Feb 27 at 1:08
  • $\begingroup$ I would write it as vec([$x$,$y$]) (divided by the norm of itself for the unit length) $\endgroup$ – LinAlg Feb 27 at 2:57
