+# gsort2hp
+
+> Simultaneously sort two one-dimensional ndarrays based on the sort order of the first ndarray using heapsort.
+
+
+
+
+
+
+
+
+
+## Usage
+
+```javascript
+var gsort2hp = require( '@stdlib/blas/ext/base/ndarray/gsort2hp' );
+```
+
+#### gsort2hp( arrays )
+
+Simultaneously sorts two one-dimensional ndarrays based on the sort order of the first ndarray using heapsort.
+
+```javascript
+var ndarray = require( '@stdlib/ndarray/base/ctor' );
+var ndarray2array = require( '@stdlib/ndarray/to-array' );
+var scalar2ndarray = require( '@stdlib/ndarray/from-scalar' );
+
+var xbuf = [ 1.0, -2.0, 3.0, -4.0 ];
+var x = new ndarray( 'generic', xbuf, [ 4 ], [ 1 ], 0, 'row-major' );
+
+var ybuf = [ 0.0, 1.0, 2.0, 3.0 ];
+var y = new ndarray( 'generic', ybuf, [ 4 ], [ 1 ], 0, 'row-major' );
+
+var ord = scalar2ndarray( 1.0, {
+ 'dtype': 'generic'
+});
+
+gsort2hp( [ x, y, ord ] );
+// x => [ -4.0, -2.0, 1.0, 3.0 ]
+// y => [ 3.0, 1.0, 0.0, 2.0 ]
+```
+
+The function has the following parameters:
+
+- **arrays**: array-like object containing two one-dimensional input ndarrays and a zero-dimensional ndarray specifying the sort order.
+
+
+
+
+
+
+
+## Notes
+
+- The input ndarrays are sorted **in-place** (i.e., the input ndarrays are **mutated**).
+- When the sort order is less than zero, the first input ndarray is sorted in **decreasing** order. When the sort order is greater than zero, the first input ndarray is sorted in **increasing** order. When the sort order is equal to zero, the input ndarrays are 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 gsort2hp = require( '@stdlib/blas/ext/base/ndarray/gsort2hp' );
+
+var xbuf = discreteUniform( 10, -100, 100, {
+ 'dtype': 'generic'
+});
+var x = new ndarray( 'generic', xbuf, [ xbuf.length ], [ 1 ], 0, 'row-major' );
+
+var ybuf = discreteUniform( 10, -100, 100, {
+ 'dtype': 'generic'
+});
+var y = new ndarray( 'generic', ybuf, [ ybuf.length ], [ 1 ], 0, 'row-major' );
+
+var ord = scalar2ndarray( 1.0, {
+ 'dtype': 'generic'
+});
+
+gsort2hp( [ x, y, ord ] );
+
+console.log( ndarray2array( x ) );
+console.log( ndarray2array( y ) );
