+# ssorthp
+
+> Sort a one-dimensional single-precision floating-point ndarray using heapsort.
+
+
+
+
+
+
+
+
+
+## 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
+
+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.
+
+
+
+
+
+
+
+## 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.
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var discreteUniform = require( '@stdlib/random/array/discrete-uniform' );
+var ndarray = require( '@stdlib/ndarray/base/ctor' );
+var scalar2ndarray = require( '@stdlib/ndarray/from-scalar' );
+var ndarray2array = require( '@stdlib/ndarray/to-array' );
+var ndarraylike2scalar = require( '@stdlib/ndarray/base/ndarraylike2scalar' );
+var ssorthp = require( '@stdlib/blas/ext/base/ndarray/ssorthp' );
+
+var xbuf = discreteUniform( 10, -100, 100, {
+ 'dtype': 'float32'
+});
+var x = new ndarray( 'float32', xbuf, [ xbuf.length ], [ 1 ], 0, 'row-major' );
+console.log( ndarray2array( x ) );
+
+var order = scalar2ndarray( 1.0, {
+ 'dtype': 'generic'
+});
+console.log( 'Order:', ndarraylike2scalar( order ) );
+
+ssorthp( [ x, order ] );
+console.log( ndarray2array( x ) );
+```

+{{alias}}( arrays )
