+## Usage
+
+```javascript
+var ssorthp = require( '@stdlib/blas/ext/base/ndarray/ssorthp' );
+```
+
+#### ssorthp( arrays )
+
+Sorts a one-dimensional single-precision floating-point ndarray using heapsort.
+
+```javascript
+var Float32Array = require( '@stdlib/array/float32' );
+var scalar2ndarray = require( '@stdlib/ndarray/from-scalar' );
+var ndarray2array = require( '@stdlib/ndarray/to-array' );
+var ndarray = require( '@stdlib/ndarray/base/ctor' );
+
+var xbuf = new Float32Array( [ 1.0, -2.0, 3.0, -4.0 ] );
+var x = new ndarray( 'float32', xbuf, [ 4 ], [ 1 ], 0, 'row-major' );
+
+var order = scalar2ndarray( 1.0, {
+    'dtype': 'generic'
+});
+
+var out = ssorthp( [ x, order ] );
+// returns <ndarray>
+
+var arr = ndarray2array( out );
+// returns [ -4.0, -2.0, 1.0, 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 sort order.
+
+</section>
+
+<!-- /.usage -->
+
+<section class="notes">
+
+## Notes
+
+-   The input ndarray is sorted **in-place** (i.e., the input ndarray is **mutated**).
+-   When the sort order is less than zero, the input ndarray is sorted in **decreasing** order. When the sort order is greater than zero, the input ndarray is sorted in **increasing** order. When the sort order is equal to zero, the input ndarray is left unchanged.

+{{alias}}( arrays )
+    Sorts a one-dimensional single-precision floating-point ndarray using
+    heapsort.
+
+    When the sort order is less than zero, the input ndarray is sorted in
+    decreasing order. When the sort order is greater than zero, the input
+    ndarray is sorted in increasing order. When the sort order is equal to zero,
+    the input ndarray is left unchanged.
+
+    The input ndarray is sorted *in-place* (i.e., the input strided array is
+    *mutated*).
+
+    Parameters
+    ----------
+    arrays: ArrayLikeObject<ndarray>
+        Array-like object containing a one-dimensional input ndarray and a
+        zero-dimensional ndarray specifying the sort order.
+
+    Returns
+    -------
+    out: ndarray
+        Input ndarray.
+
+    Examples
+    --------
+    > var xbuf = [ 1.0, -2.0, 3.0, -4.0 ];
+    > var dt = 'float32';
+    > 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 o = {{alias:@stdlib/ndarray/from-scalar}}( 1.0, { 'dtype': dt } );
+    > {{alias}}( [ x, o ] )
+    <ndarray>
+    > var data = x.data
+    [ -4.0, -2.0, 1.0, 3.0 ]
