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.
