# mesh

3D mesh plot

### Syntax

mesh(Z) mesh(X,Y,Z) mesh(...,<GlobalProperty>) mesh(...,<color>,<GlobalProperty>) mesh(<axes_handle>,...)

### Arguments

- Z
a real matrix defining the surface height. It can not be omitted. The

`Z`

data is a`m`

-by-`n`

matrix.- X, Y
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).- color
an optional real matrix defining a color value for each

`(X(j),Y(i))`

point of the grid (see description below).- <GlobalProperty>
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).- <axes_handle>
this optional argument forces the plot to appear inside the selected axes given by

`axes_handle`

rather than the current axes (see gca).

### Description

`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.

### Remarks

To enable the transparency mode you should set the
`color_mode`

option to 0.
