    About stdlib...
  </summary>
  <p>We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.</p>
  <p>The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.</p>
  <p>When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.</p>
  <p>To join us in bringing numerical computing to the web, get started by checking us out on <a href="https://github.com/stdlib-js/stdlib">GitHub</a>, and please consider <a href="https://opencollective.com/stdlib">financially supporting stdlib</a>. We greatly appreciate your continued support!</p>

<!-- /.intro -->

<section class="installation">

## Installation

```bash
npm install @stdlib/stats-base-ndarray-dmediansorted
```

</section>

<section class="usage">

## Usage

```javascript
var dmediansorted = require( '@stdlib/stats-base-ndarray-dmediansorted' );
```

#### dmediansorted( arrays )

Computes the median value of a sorted one-dimensional double-precision floating-point ndarray.

```javascript
var Float64Array = require( '@stdlib/array-float64' );
var ndarray = require( '@stdlib/ndarray-base-ctor' );

var xbuf = new Float64Array( [ 1.0, 2.0, 3.0 ] );
var x = new ndarray( 'float64', xbuf, [ 3 ], [ 1 ], 0, 'row-major' );

var v = dmediansorted( [ x ] );
// returns 2.0
```

The function has the following parameters:

-   **arrays**: array-like object containing a sorted one-dimensional input ndarray.

</section>

<!-- /.usage -->

<section class="notes">

## Notes

-   If provided an empty ndarray, the function returns `NaN`.
-   The one-dimensional input ndarray must be sorted in either **strictly** ascending or descending order.

</section>

<!-- /.notes -->

<section class="examples">

## Examples

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

```javascript
var linspace = require( '@stdlib/array-linspace' );
var ndarray = require( '@stdlib/ndarray-base-ctor' );
var ndarray2array = require( '@stdlib/ndarray-to-array' );
var dmediansorted = require( '@stdlib/stats-base-ndarray-dmediansorted' );

// Create a linearly spaced sorted array:
var xbuf = linspace( 0.0, 10.0, 11, {
    'dtype': 'float64'
});

var x = new ndarray( 'float64', xbuf, [ xbuf.length ], [ 1 ], 0, 'row-major' );
console.log( ndarray2array( x ) );

var v = dmediansorted( [ x ] );
console.log( v );
```
