plot3d: Plot 3-d surface plot
      Plots a three dimensional surface plot within the environment set up
      by plw3d.  The surface is defined by the two-dimensional array
      z[nx][ny],
      the point z[i][j] being the
      value of the function at (x[i],
      y[j]).  Note that the points in
      arrays x and
      y do not need to be equally
      spaced, but must be stored in ascending order.  The parameter
      opt controls the way in
      which the surface is displayed.  For further details see the Section called Three Dimensional Surface Plots in Chapter 3.
      The only difference between plmesh and plot3d is that plmesh draws
      the botton side of the surface, while plot3d only draws the surface as
      viewed from the top.
