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(3plplot).  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(3plplot)  and
       plot3d(3plplot) is that plmesh(3plplot) draws the bottom side of the surface, while plot3d(3plplot)  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 (const PLFLT *, input)
              Pointer to set of x coordinate values at which the function is evaluated.

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

       z (const PLFLT * const *, 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.
