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 fur-
       ther 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 (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.
