# Special Functions

> Special math functions applied to arrays.

<section class="usage">

## Usage

```javascript
var ns = require( '@stdlib/math/array/special' );
```

#### ns

Namespace containing special math functions applied to arrays.

```javascript
var o = ns;
// returns {...}
```

The namespace contains the following:

<!-- <toc pattern="*"> -->

<div class="namespace-toc">

-   <span class="signature">[`abs( x[, options] )`][@stdlib/math/array/special/abs]</span><span class="delimiter">: </span><span class="description">compute the absolute value for each element in an input array.</span>

</div>

<!-- </toc> -->

## Examples

<!-- eslint no-undef: "error" -->

```javascript
var ns = require( '@stdlib/math/array/special' );

// Create an input array:
var x = [ -1.0, 2.0, -3.0, 4.0 ];

// Perform element-wise computation:
var out = ns.abs( x );
// returns [ 1.0, 2.0, 3.0, 4.0 ]
```
