    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>

> Generate a linearly spaced numeric array whose elements increment by 1 starting from zero.

<section class="installation">

## Installation

```bash
npm install @stdlib/array-base-zero-to
```

</section>

<section class="usage">

## Usage

```javascript
var zeroTo = require( '@stdlib/array-base-zero-to' );
```

#### zeroTo( n )

Generates a linearly spaced numeric array whose elements increment by `1` starting from zero.

```javascript
var arr = zeroTo( 6 );
// returns [ 0, 1, 2, 3, 4, 5 ]
```

If `n <= 0`, the function returns an empty array.

```javascript
var arr = zeroTo( 0 );
// returns []

arr = zeroTo( -1 );
// returns []
```

If `n` is a non-integer value greater than zero, the function returns an array having `ceil(n)` elements.

```javascript
var arr = zeroTo( 5.1 );
// returns [ 0, 1, 2, 3, 4, 5 ]
```

#### zeroTo.assign( out, stride, offset )

Fills an array with linearly spaced numeric elements which increment by 1 starting from zero.

```javascript
var out = [ 0, 0, 0, 0, 0, 0 ];

var arr = zeroTo.assign( out, -1, out.length-1 );
// returns [ 5, 4, 3, 2, 1, 0 ]

var bool = ( arr === out );
// returns true
```

## Examples

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

```javascript
var sort2hp = require( '@stdlib/blas-ext-base-gsort2hp' );
var filledBy = require( '@stdlib/array-base-filled-by' );
var randu = require( '@stdlib/random-base-randu' );
var zeroTo = require( '@stdlib/array-base-zero-to' );

// Generate an array of random numbers:
var x = filledBy( 10, randu );

// Generate an array of indices:
var idx = zeroTo( x.length );

// Create a temporary array to avoid mutation:
var tmp = x.slice();

// Sort the index array according to the sort order of `x`:
sort2hp( x.length, 1, tmp, 1, idx, 1 );

console.log( x );
console.log( idx );
```
