** Syntax**

**Description**

`brighten`

increases or decreases the color intensities in a colormap. The modified colormap is brighter if` 0 < beta < 1`

and darker if` -1 < beta < 0`

.

```
brighten(beta)
```

replaces the current colormap with a brighter or darker colormap of essentially the same colors. `brighten(beta)`

, followed by `brighten(-beta)`

, where `beta < 1`

, restores the original map.

```
brighten(h,beta)
```

brightens all objects that are children of the figure having the handle `h`

.

```
newmap = brighten(beta)
```

returns a brighter or darker version of the current colormap without changing the display.

```
newmap = brighten(cmap,beta)
```

returns a brighter or darker version of the colormap `cmap`

without changing the display.

**Examples**

Brighten and then darken the current colormap:

**Algorithm**

The values in the colormap are raised to the power of gamma, where gamma is
