- X, Y, Z:
3 real matrices defining a data structure.
a real vector.
This represents a sequence of statements
key1=value1, key2=value2,... where
key2,...can be one of the following: theta, alpha ,leg,flag,ebox (see definition below).
- theta, alpha
real values giving in degree the spherical coordinates of the observation point.
string defining the labels for each axis with @ as a field separator, for example "X@Y@Z".
a real vector of size four.
an integer (surface color), default is 3.
Colormap index defining the color used to draw vertical edges.
an integer (surface color), default is 4.
Colormap index defining the color used to draw horizontal edges.
an integer (scaling) default is 2.
the plot is made using the current 3D scaling (set by a previous call to

only the axes behind the surface are drawn.
a box surrounding the surface is drawn and captions are added.

Note that axes aspect can also be customized through the axes entity properties (see axes_properties).
It specifies the boundaries of the plot as the vector
[xmin,xmax,ymin,ymax,zmin,zmax]. This argument is used together with
flag: if it is set to

eboxargument acts on the
data_boundsfield that can also be reset through the axes entity properties (see axes_properties).
plot3d3 performs a mesh plot of a surface defined by
rectangular facets. (X,Y,Z) are three matrices which describe a surface.
The surface is composed of four sided polygons.
The X-coordinates of a facet are given by X(i,j), X(i+1,j), X(i+1,j+1) and X(i,j+1). Similarly Y and Z matrices contain Y and Z-coordinates.
vect vector is used when multiple surfaces are coded
in the same (X,Y,Z) matrices.
vect(j) gives the line at which
the coding of the jth surface begins. See
plot3d2 for a full
description. As a mesh plot, the only available property you can edit is
visible option (see axes_properties).
