+## Usage
+
+```javascript
+var doneTo = require( '@stdlib/blas/ext/base/ndarray/done-to' );
+```
+
+#### doneTo( arrays )
+
+Fills a one-dimensional double-precision floating-point ndarray with linearly spaced numeric elements which increment by `1` starting from one.
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+var ndarray = require( '@stdlib/ndarray/base/ctor' );
+
+var xbuf = new Float64Array( [ 0.0, 0.0, 0.0, 0.0 ] );
+var x = new ndarray( 'float64', xbuf, [ 4 ], [ 1 ], 0, 'row-major' );
+// returns <ndarray>[ 0.0, 0.0, 0.0, 0.0 ]
+
+var out = doneTo( [ x ] );
+// returns <ndarray>[ 1.0, 2.0, 3.0, 4.0 ]
+```
+
+The function has the following parameters:
+
+-   **arrays**: array-like object containing a one-dimensional input ndarray.
