3D mesh plot
mesh(Z) mesh(X,Y,Z) mesh(...,<GlobalProperty>) mesh(...,<color>,<GlobalProperty>) mesh(<axes_handle>,...)
a real matrix defining the surface height. It can not be
omitted. The Z
data is a
m
-by-n
matrix.
two real matrices : always set together, these data defines a
new standard grid. This new X
and Y
components of the grid must match Z
dimensions (see
description below).
an optional real matrix defining a color value for each
(X(j),Y(i))
point of the grid (see description
below).
this optional argument represents a sequence of couple
statements {PropertyName,PropertyValue}
that defines
global objects' properties applied to all the curves created by this
plot. For a complete view of the available properties (see
GlobalProperty).
this optional argument forces the plot to appear inside the
selected axes given by axes_handle
rather than the
current axes (see gca).
mesh
draws a parametric surface using a rectangular grid
defined by X
and Y
coordinates (if
{X,Y}
are not specified, this grid is determined using the
dimensions of the Z
matrix); at each point of this grid, a z
coordinate is given using the Z
matrix. mesh
is
based on the surf
command with default option
color_mode
= white index (inside the current colormap) and
color_flag
= 0.
Data entry specification :
In this paragraph and to be more clear, we won't mention
GlobalProperty
optional arguments as they do not interfere
with entry data (except for "Xdata"
,
"Ydata"
and "Zdata"
property, see GlobalProperty). It is
assumed that all those optional arguments could be present too.
If Z
is the only matrix specified, mesh(Z)
plots the matrix Z
versus the grid defined by
1:size(Z,2)
along the x axis and 1:size(Z,1)
along the y axis.
To enable the transparency mode you should set the
color_mode
option to 0.

6.0.2 | The "Foreground", "markForeground", and "markBackground" global properties colors can now be specified as named colors chosen in the full predefined colors list, or by their "#RRGGBB" hexadecimal codes, or by their colormap indices. |
