    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>

## Usage

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

#### copy( x )

Copies an input ndarray to a new ndarray having the same shape and [data type][@stdlib/ndarray/dtypes].

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

var x = zeros( 'float64', [ 2, 2 ], 'row-major' );
// returns <ndarray>

var y = copy( x );
// returns <ndarray>

var sh = getShape( y );
// returns [ 2, 2 ]
```

## Notes

-   The function performs a full copy in which an ndarray's underlying data is copied to a new underlying data buffer.
-   Along with data type, shape, and order, the function infers the "class" of the returned ndarray from the provided ndarray. For example, if provided a "base" [ndarray][@stdlib/ndarray/base/ctor], the function returns a base [ndarray][@stdlib/ndarray/base/ctor]. If provided a non-base [ndarray][@stdlib/ndarray/ctor], the function returns a non-base [ndarray][@stdlib/ndarray/ctor].

## Examples

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

```javascript
var bernoulli = require( '@stdlib/random-array-bernoulli' );
var array = require( '@stdlib/ndarray-array' );
var ndarray2array = require( '@stdlib/ndarray-to-array' );
var copy = require( '@stdlib/ndarray-base-copy' );

var xbuf = bernoulli( 10, 0.9, {
    'dtype': 'generic'
});
var x = array({
    'dtype': 'generic',
    'data': xbuf,
    'shape': [ 5, 2 ],
    'strides': [ 2, 1 ],
    'offset': 0,
    'order': 'row-major'
});
console.log( ndarray2array( x ) );

var o = copy( x );
console.log( ndarray2array( o ) );
