CREATESCALING3D Create the 4x4 matrix of a 3D scaling.

   TRANS = createScaling3d(S);
   returns the scaling transform corresponding to a scaling factor S in
   each direction. S can be a scalar, or a 1-by-3 vector containing the
   scaling factor in each direction.

   TRANS = createScaling3d(SX, SY, SZ);
   returns the scaling transform corresponding to a different scaling
   factor in each direction.

   The returned matrix has the form :
   [SX  0  0  0]
   [ 0 SY  0  0]
   [ 0  0 SZ  0]
   [ 0  0  0  0]
