# gzeroTo

> Fill a one-dimensional ndarray with linearly spaced numeric elements which increment by `1` starting from zero.

<section class="intro">

</section>

<!-- /.intro -->

<section class="usage">

## Usage

```javascript
var gzeroTo = require( '@stdlib/blas/ext/base/ndarray/gzero-to' );
```

#### gzeroTo( arrays )

Fills a one-dimensional ndarray with linearly spaced numeric elements which increment by `1` starting from zero.

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

var xbuf = [ 0.0, 0.0, 0.0, 0.0 ];
var x = new ndarray( 'generic', xbuf, [ 4 ], [ 1 ], 0, 'row-major' );
// returns <ndarray>[ 0.0, 0.0, 0.0, 0.0 ]

var out = gzeroTo( [ x ] );
// returns <ndarray>[ 0.0, 1.0, 2.0, 3.0 ]
```

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 zeros = require( '@stdlib/array/zeros' );
var ndarray = require( '@stdlib/ndarray/base/ctor' );
var ndarray2array = require( '@stdlib/ndarray/to-array' );
var gzeroTo = require( '@stdlib/blas/ext/base/ndarray/gzero-to' );

var xbuf = zeros( 10, 'generic' );
var x = new ndarray( 'generic', xbuf, [ xbuf.length ], [ 1 ], 0, 'row-major' );
console.log( ndarray2array( x ) );

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

{{alias}}( arrays )
Fills a one-dimensional ndarray with linearly spaced numeric elements which
increment by `1` starting from zero.

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 xbuf = [ 0.0, 0.0, 0.0, 0.0 ];
> var dt = 'generic';
> var sh = [ xbuf.length ];
> var sx = [ 1 ];
> var ox = 0;
> var ord = 'row-major';
> var x = new {{alias:@stdlib/ndarray/ctor}}( dt, xbuf, sh, sx, ox, ord );
> {{alias}}( [ x ] )
<ndarray>[ 0.0, 1.0, 2.0, 3.0 ]
