    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/blas-ext-base-ndarray-zsum
```

</section>

<section class="usage">

## Usage

```javascript
var zsum = require( '@stdlib/blas-ext-base-ndarray-zsum' );
```

#### zsum( arrays )

Computes the sum of all elements in a one-dimensional double-precision complex floating-point ndarray.

```javascript
var Complex128Array = require( '@stdlib/array-complex128' );
var ndarray = require( '@stdlib/ndarray-base-ctor' );

var xbuf = new Complex128Array( [ 1.0, 3.0, 4.0, 2.0 ] );
var x = new ndarray( 'complex128', xbuf, [ 2 ], [ 1 ], 0, 'row-major' );

var v = zsum( [ x ] );
// returns <Complex128>[ 5.0, 5.0 ]
```

The function has the following parameters:

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

<section class="notes">

## Notes

-   If provided an empty one-dimensional ndarray, the function returns `0.0 + 0.0i`.

</section>

<!-- /.notes -->

<section class="examples">

## Examples

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

```javascript
var discreteUniform = require( '@stdlib/random-array-discrete-uniform' );
var Complex128Array = require( '@stdlib/array-complex128' );
var ndarray = require( '@stdlib/ndarray-base-ctor' );
var ndarray2array = require( '@stdlib/ndarray-to-array' );
var zsum = require( '@stdlib/blas-ext-base-ndarray-zsum' );

var xbuf = discreteUniform( 10, -50, 50, {
    'dtype': 'float64'
});
xbuf = new Complex128Array( xbuf );

var x = new ndarray( 'complex128', xbuf, [ xbuf.length ], [ 1 ], 0, 'row-major' );
console.log( ndarray2array( x ) );

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