## Usage
34+
35+
```javascript
36+
var maxsorted = require( '@stdlib/stats/array/maxsorted' );
37+
```
38+
39+
#### maxsorted( x )
40+
41+
Computes the maximum value of a sorted array.
42+
43+
```javascript
44+
var x = [ 1.0, 2.0, 3.0 ];
45+
46+
var v = maxsorted( x );
47+
// returns 3.0
48+
49+
x = [ 3.0, 2.0, 1.0 ];
50+
51+
v = maxsorted( x );
52+
// returns 3.0
53+
```
54+
55+
The function has the following parameters:
56+
57+
- **x**: input array.
58+
59+
</section>
60+
61+
<!-- /.usage -->
62+
63+
<section class="notes">
64+
65+
## Notes
66+
67+
- If provided an empty array, the function returns `NaN`.
68+
- The function supports array-like objects having getter and setter accessors for array element access (e.g., [`@stdlib/array/base/accessor`][@stdlib/array/base/accessor]).
