26 ## Plot a 3-D surface mesh.
27 ##
28 ## The surface mesh is plotted using shaded rectangles. The vertices of the
29 ## rectangles [@var{x}, @var{y}] are typically the output of @code{meshgrid}.
30 ## over a 2-D rectangular region in the x-y plane. @var{z} determines the
31 ## height above the plane of each vertex. If only a single @var{z} matrix is
32 ## given, then it is plotted over the meshgrid
33 ## @code{@var{x} = 1:columns (@var{z}), @var{y} = 1:rows (@var{z})}.
34 ## Thus, columns of @var{z} correspond to different @var{x} values and rows
35 ## of @var{z} correspond to different @var{y} values.
36 ##
37 ## The color of the surface is computed by linearly scaling the @var{z} values
38 ## to fit the range of the current colormap. Use @code{caxis} and/or
39 ## change the colormap to control the appearance.
40 ##
41 ## Optionally, the color of the surface can be specified independently of
42 ## @var{z} by supplying a color matrix, @var{c}.
43 ##
44 ## Any property/value pairs are passed directly to the underlying surface
45 ## object.
46 ##
47 ## If the first argument @var{hax} is an axes handle, then plot into this axis,
48 ## rather than the current axes returned by @code{gca}.
49 ##
50 ## The optional return value @var{h} is a graphics handle to the created
51 ## surface object.
52 ##
53 ## Note: The exact appearance of the surface can be controlled with the
54 ## @code{shading} command or by using @code{set} to control surface object
55 ## properties.
