**Syntax**

**Description**

The position of the viewer (the viewpoint) determines the orientation of the axes. You specify the viewpoint in terms of azimuth and elevation, or by a point in three-dimensional space.

```
view(az,el) and view([az,el])
```

set the viewing angle for a three-dimensional plot. The azimuth, `az`

, is the horizontal rotation about the *z*-axis as measured in degrees from the negative *y*-axis. Positive values indicate counterclockwise rotation of the viewpoint. `el`

is the vertical elevation of the viewpoint in degrees. Positive values of elevation correspond to moving above the object; negative values correspond to moving below the object.

```
view([x,y,z])
```

sets the viewpoint to the Cartesian coordinates `x`

, `y`

, and `z`

. The magnitude of `(x,y,z)`

is ignored.

```
view(2)
```

sets the default two-dimensional view, `az = 0,`

`el = 90`

.

```
view(3)
```

sets the default three-dimensional view, `az = -37.5,`

`el = 30`

.

```
view(T)
```

sets the view according to the transformation matrix `T`

, which is a 4-by-4 matrix such as a perspective transformation generated by `viewmtx`

.

```
[az,el] = view
```

returns the current azimuth and elevation.

```
T = view
```

returns the current 4-by-4 transformation matrix.

**Remarks**

Azimuth is a polar angle in the *x-y* plane, with positive angles indicating counterclockwise rotation of the viewpoint. Elevation is the angle above (positive angle) or below (negative angle) the *x-y* plane.

This diagram illustrates the coordinate system. The arrows indicate positive directions.

**Examples**

View the object from directly overhead.

Set the view along the *y**-*axis, with the *x-*axis extending horizontally and the *z-*axis extending vertically in the figure.

Rotate the view about the *z-*axis by 180º.
