	)

Plots a 3-d representation of the virtual function z, which is represented by zops and zp.

Parameters

x	The x values are stored as x[0..nx-1]
y	The y values are stored as y[0..ny-1]
zops	Pointer to a plf2ops_t structure of function pointers (see plf2opts_t in plplot.h) which define how to perform various manipulations (including retrieval) on the elements of the the 2D data field pointed to by zp. Pointers suitable for passing as zops can be obtained for some predefined types of 2-d data storage by calling one of the plf2ops_*() functions (see plf2ops.c) or you can create your own set for arbitrary 2-d storage formats.
zp	Pointer to 2D data field. This pointer is passed to the functions of zops whenever the 2D field needs to be manipulated. The combination of zops and zp provides total flexibility in how the underlying data values are managed.
nx	The number of values in x.
ny	The number of values in y.
opt	Specifies options for the plot. It can be a bitwise OR-ing of these: DRAW_LINEX : Draw lines parallel to x-axis DRAW_LINEY : Draw lines parallel to y-axis DRAW_LINEXY: Draw lines parallel to both axes MAG_COLOR: Magnitude coloring of wire frame BASE_CONT: Draw contour at bottom xy plane TOP_CONT: Draw contour at top xy plane (not yet) DRAW_SIDES: Draw sides around the plot MESH: Draw the "under" side of the plot or any bitwise OR'd combination, e.g. "MAG_COLOR | DRAW_LINEX"
clevel	z values at which to draw contours
nlevel	Number of values in clevels
PL_UNUSED(	indexxmin ) Not used.
PL_UNUSED(	indexxmax ) Not used.
PL_UNUSED(	indexymin ) Not used.
PL_UNUSED(	indexymax ) Not used.
