    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 according to a provided increment.

<section class="installation">

## Installation

```bash
npm install @stdlib/array-base-incrspace
```

</section>

<section class="usage">

## Usage

```javascript
var incrspace = require( '@stdlib/array-base-incrspace' );
```

#### incrspace( start, stop, increment )

Generates a linearly spaced numeric `array` according to a provided `increment`.

```javascript
var arr = incrspace( 0, 11, 2 );
// returns [ 0, 2, 4, 6, 8, 10 ]
```

</section>

<!-- /.usage -->

<section class="notes">

### Notes

-   The output `array` is guaranteed to include the `start` value but does **not** include the `stop` value. Beware that values subsequent to the `start` value are subject to floating-point errors. Hence,

    ```javascript
    var arr = incrspace( 0.1, 0.5, 0.2 );
    // returns [ 0.1, ~0.3 ]
    ```

    where `arr[1]` is only guaranteed to be approximately equal to `0.3`.

    If you desire more control over element precision, consider using [roundn][@stdlib/math/base/special/roundn]:

    ```javascript
    var roundn = require( '@stdlib/math-base-special-roundn' );

    // Create an array subject to floating-point errors:
    var arr = incrspace( 0, 1.01, 0.02 );

    // Round each value to the nearest hundredth:
    var i;
    for ( i = 0; i < arr.length; i++ ) {
        arr[ i ] = roundn( arr[ i ], -2 );
    }

    console.log( arr.join( '\n' ) );
    ```

## Examples

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

```javascript
var incrspace = require( '@stdlib/array-base-incrspace' );

var out = incrspace( 0, 10, 2 );
console.log( out.join( '\n' ) );

out = incrspace( 0, 11, 2 );
console.log( out.join( '\n' ) );

out = incrspace( 0, 1.01, 0.02 );
console.log( out.join( '\n' ) );

// Create an array using a negative increment:
out = incrspace( 10, 0, -2 );
console.log( out.join( '\n' ) );
```
