meshFaceNumber

MESHFACENUMBER Returns the number of faces in this mesh.

   NF = meshFaceNumber(V, F)
   NF = meshFaceNumber(V, E, F)
   NF = meshFaceNumber(MESH)
   Returns the number of faces in the given mesh. As the face array may be
   represented either as numeric array or as cell array of indices, this
   function is a convenient way to get the number of faces independanlty
   of the mesh representation.

   Example
     [v f] = createCube;
     meshFaceNumber(v, f)
     ans =
         6
