+## Usage
+
+```javascript

+
+#### gcopy( arrays )
+
+Copies values from a one-dimensional ndarray `x` into a one-dimensional ndarray `y`.
+
+```javascript
+var ndarray = require( '@stdlib/ndarray/base/ctor' );
+
+var xbuf = [ 1.0, 2.0, 3.0, 4.0, 5.0 ];
+var x = new ndarray( 'generic', xbuf, [ 5 ], [ 1 ], 0, 'row-major' );
+
+var ybuf = [ 0.0, 0.0, 0.0, 0.0, 0.0 ];
+var y = new ndarray( 'generic', ybuf, [ 5 ], [ 1 ], 0, 'row-major' );

+var z = gcopy( [ x, y ] );
+// returns <ndarray>[ 1.0, 2.0, 3.0, 4.0, 5.0 ]
+
+var bool = ( y === z );
+// returns true
+```
+
+The function has the following parameters:
+
+-   **arrays**: array-like object containing an input ndarray and an output ndarray.
