> Fill a one-dimensional double-precision floating-point ndarray with ones.

<section class="intro">

</section>

<!-- /.intro -->

<section class="usage">

## Usage

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

#### dones( arrays )

Fills a one-dimensional double-precision floating-point ndarray with ones.

```javascript
var Float64Vector = require( '@stdlib/ndarray/vector/float64' );

var x = new Float64Vector( [ 0.0, 0.0, 0.0, 0.0 ] );
// returns <ndarray>[ 0.0, 0.0, 0.0, 0.0 ]

var out = dones( [ x ] );
// returns <ndarray>[ 1.0, 1.0, 1.0, 1.0 ]
```

The function has the following parameters:

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

</section>

<!-- /.usage -->

<section class="notes">

## Notes

- The input ndarray is modified **in-place** (i.e., the input ndarray is **mutated**).

</section>

<!-- /.notes -->

<section class="examples">

## Examples

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

```javascript
var Float64Vector = require( '@stdlib/ndarray/vector/float64' );
var ndarray2array = require( '@stdlib/ndarray/to-array' );
var dones = require( '@stdlib/blas/ext/base/ndarray/dones' );

var x = new Float64Vector( 10 );
console.log( ndarray2array( x ) );

dones( [ x ] );
console.log( ndarray2array( x ) );
```

{{alias}}( arrays )
Fills a one-dimensional double-precision floating-point ndarray with ones.

The input ndarray is modified *in-place* (i.e., the input ndarray is
*mutated*).

Parameters
----------
arrays: ArrayLikeObject<ndarray>
Array-like object containing a one-dimensional input ndarray.

Returns
-------
out: ndarray
Input ndarray.

Examples
--------
> var x = new {{alias:@stdlib/ndarray/vector/float64}}( [ 0.0, 0.0, 0.0, 0.0 ] );
> {{alias}}( [ x ] )
<ndarray>[ 1.0, 1.0, 1.0, 1.0 ]
