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 matrix z[nx][ny] , the point z[i][j] being the value of the function at (x[i],y[j]).  Note
       that  the  points  in  vectors  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 and 21.

ARGUMENTS

       x (PLFLT_VECTOR(3plplot), input)
              A vector containing the x coordinates at which the function is evaluated.

       y (PLFLT_VECTOR(3plplot), input)
              A vector containing the y coordinates at which the function is evaluated.

       z (PLFLT_MATRIX(3plplot), input)
              A matrix containing function values to plot.  Should have dimensions of nx by ny.

       nx (PLINT(3plplot), input)
              Number of x values at which function is evaluated.

       ny (PLINT(3plplot), input)
              Number of y values at which function is evaluated.

       opt (PLINT(3plplot), 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(3plplot), 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.
