# contour3

Creates 3D contoured surface in an axes.

## Syntax

contour3(z)

contour3(x, y, z)

contour3(hAxes, ...)

## Inputs

`x, y, z`- Range of the x, y and z axes.
`hAxes`- Axis handle.

## Example

Contour3 plot example:

```
cla;
x=[0:0.1:2*pi];
y=x;
z=sin(x')*cos(y);
contour3(z)
```

## Comments

If there is no axes, one will be created first. If `x` and
`y` are omitted, the index of the columns of `z` is used
for x coordinates and the index of the rows of z is used for y coordinates.
contour3 () takes optional arguments to control the surface style. It
can be either the contour levels or the contour line style, or both. If the first argument
of contour3 () is an axes handle, surfaces will be created in that
axes.
