Plot a surface graphic object given matrices x, and y from
meshgrid
and a matrix z corresponding to the x and y coordinates of the surface. If x and y are vectors, then a typical vertex is (x(j), y(i), z(i,j)). Thus, columns of z correspond to different x values and rows of z correspond to different y values. If x and y are missing, they are constructed from size of the matrix z.Any additional properties passed are assigned the the surface..
