+## Usage
+
+```javascript
+var gcircshift = require( '@stdlib/blas/ext/base/ndarray/gcircshift' );
+```
+
+#### gcircshift( arrays )
+
+Circularly shifts the elements of a one-dimensional ndarray by a specified number of positions.
+
+```javascript
+var scalar2ndarray = require( '@stdlib/ndarray/from-scalar' );
+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 k = scalar2ndarray( 2, {
+    'dtype': 'generic'
+});
+
+var out = gcircshift( [ x, k ] );
+// returns <ndarray>[ 4.0, 5.0, 1.0, 2.0, 3.0 ]
+```
+
+The function has the following parameters:
+
+-   **arrays**: array-like object containing a one-dimensional input ndarray and a zero-dimensional ndarray specifying the number of positions to shift.

+
+<!-- /.usage -->

+{{alias}}( arrays )
+    Circularly shifts the elements of a one-dimensional ndarray by a specified
+    number of positions.
+
+    The input ndarray is shifted *in-place* (i.e., the input ndarray is
+    *mutated*).
+
+    Parameters
+    ----------
+    arrays: ArrayLikeObject<ndarray>
+        Array-like object containing the following ndarrays:
+
+        - a one-dimensional input ndarray.
+        - a zero-dimensional ndarray specifying the number of positions to
+        shift.
+
+    Returns
+    -------
+    out: ndarray
+        Input ndarray.
+
+    Examples
+    --------
+    > var xbuf = [ 1.0, 2.0, 3.0, 4.0 ];
+    > 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 );
+    > var k = {{alias:@stdlib/ndarray/from-scalar}}( 2, { 'dtype': dt } );
+    > {{alias}}( [ x, k ] )
+    <ndarray>
+    > var data = x.data
+    [ 3.0, 4.0, 1.0, 2.0 ]
