NAME
       plot3d - Plot 3-d surface plot

SYNOPSIS
       plot3d(x, y, z, nx, ny, opt, side)

DESCRIPTION
       Plots a three dimensional surface plot within the environment set up by
       plw3d(3).   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  PLplot  documentation.  The  only difference between
       plmesh(3) and plot3d(3) is that plmesh(3) draws the bottom side of  the
       surface, while plot3d(3) only draws the surface as viewed from the top.

       Redacted form: plot3d(x, y, z, opt, side)

       This function is used in examples 11,21.

ARGUMENTS
       x (PLFLT *, input)
              Pointer to set of x coordinate values at which the  function  is
              evaluated.

       y (PLFLT *, input)
              Pointer  to  set of y coordinate values at which the function is
              evaluated.

       z (PLFLT **, input)
              Pointer to a vectored two-dimensional array with set of function
              values.

       nx (PLINT, input)
              Number of x values at which function is evaluated.

       ny (PLINT, input)
              Number of y values at which function is evaluated.

       opt (PLINT, input)
              Determines   the  way  in  which  the  surface  is  represented:
              opt=DRAW_LINEX: Lines are drawn showing z as a function of x for
              each  value  of y[j].  opt=DRAW_LINEY: Lines are drawn showing z
              as a function of y for each  value  of  x[i].   opt=DRAW_LINEXY:
              Network of lines is drawn connecting points at which function is
              defined.


       side (PLBOOL, input)
              Flag to indicate whether or not ``sides'' should be draw on  the
              figure.  If side is true sides are drawn, otherwise no sides are
              drawn.
