+# dfill
+
+> Fill a one-dimensional double-precision floating-point ndarray with a specified scalar constant.
+
+
+
+
+
+
+
+
+
+## Usage
+
+```javascript
+var dfill = require( '@stdlib/blas/ext/base/ndarray/dfill' );
+```
+
+#### dfill( alpha, arrays )
+
+Fills a one-dimensional double-precision floating-point ndarray with a specified scalar constant.
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+var ndarray = require( '@stdlib/ndarray/base/ctor' );
+
+var xbuf = new Float64Array( [ 1.0, 3.0, 4.0, 2.0 ] );
+var x = new ndarray( 'float64', xbuf, [ 4 ], [ 1 ], 0, 'row-major' );
+
+dfill( 5.0, [ x ] );
+// x => [ 5.0, 5.0, 5.0, 5.0 ]
+```
+
+The function has the following parameters:
+
+- **alpha**: scalar constant.
+- **arrays**: array-like object containing a one-dimensional input ndarray.
+
+
+
+
+
+
+
+## Notes
+
+- If provided an empty one-dimensional ndarray, the function returns the input ndarray unchanged.
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var discreteUniform = require( '@stdlib/random/array/discrete-uniform' );
+var ndarray = require( '@stdlib/ndarray/base/ctor' );
+var ndarray2array = require( '@stdlib/ndarray/to-array' );
+var dfill = require( '@stdlib/blas/ext/base/ndarray/dfill' );
+
+var xbuf = discreteUniform( 10, -50, 50, {
+ 'dtype': 'float64'
+});
+var x = new ndarray( 'float64', xbuf, [ xbuf.length ], [ 1 ], 0, 'row-major' );
+console.log( ndarray2array( x ) );
+
+dfill( 5.0, [ x ] );
+console.log( ndarray2array( x ) );
+```
