    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>

## Installation

```bash
npm install @stdlib/ndarray-zeros
```

</section>

<section class="usage">

## Usage

```javascript
var zeros = require( '@stdlib/ndarray-zeros' );
```

#### zeros( shape\[, options] )

Creates a zero-filled [ndarray][@stdlib/ndarray/ctor] having a specified shape and [data type][@stdlib/ndarray/dtypes].

```javascript
var arr = zeros( [ 2, 2 ] );
// returns <ndarray>

var sh = arr.shape;
// returns [ 2, 2 ]

var dt = arr.dtype;
// returns 'float64'
```

The specified output [ndarray][@stdlib/ndarray/ctor] `shape` may be either an array-like object or an integer value.

```javascript
var arr = zeros( 2 );
// returns <ndarray>

var sh = arr.shape;
// returns [ 2 ]

var dt = arr.dtype;
// returns 'float64'
```

The function accepts the following `options`:

-   **dtype**: underlying [data type][@stdlib/ndarray/dtypes]. Must be a numeric [data type][@stdlib/ndarray/dtypes] or "generic". Default: `'float64'`.
-   **order**: specifies whether an [ndarray][@stdlib/ndarray/ctor] is `'row-major'` (C-style) or `'column-major'` (Fortran-style). Default: `'row-major'`.
-   **mode**: specifies how to handle indices which exceed array dimensions (see [`ndarray`][@stdlib/ndarray/ctor]). Default: `'throw'`.
-   **submode**: a mode array which specifies for each dimension how to handle subscripts which exceed array dimensions  (see [`ndarray`][@stdlib/ndarray/ctor]). If provided fewer modes than dimensions, the constructor recycles modes using modulo arithmetic. Default: `[ options.mode ]`.
-   **readonly**: `boolean` indicating whether an array should be **read-only**. Default: `false`.

By default, the function returns an [ndarray][@stdlib/ndarray/ctor] having a [`float64`][@stdlib/ndarray/dtypes] data type. To specify an alternative [data type][@stdlib/ndarray/dtypes], provide a `dtype` option.

```javascript
var arr = zeros( [ 2, 2 ], {
    'dtype': 'float32'
});
// returns <ndarray>

var sh = arr.shape;
// returns [ 2, 2 ]

var dt = arr.dtype;
// returns 'float32'
```
