+# zwxsy
+
+> Subtract elements of a second one-dimensional double-precision complex floating-point ndarray from the corresponding elements of a first one-dimensional double-precision complex floating-point ndarray and assign the results to elements in a third one-dimensional double-precision complex floating-point ndarray.
+
+
+
+This BLAS extension implements the operation
+
+
+
+```math
+\mathbf{w} = \mathbf{x} - \mathbf{y}
+```
+
+
+
+
+
+
+
+
+
+## Usage
+
+```javascript
+var zwxsy = require( '@stdlib/blas/ext/base/ndarray/zwxsy' );
+```
+
+#### zwxsy( arrays )
+
+Subtracts elements of a second one-dimensional double-precision complex floating-point ndarray from the corresponding elements of a first one-dimensional double-precision complex floating-point ndarray and assigns the results to elements in a third one-dimensional double-precision complex floating-point ndarray.
+
+```javascript
+var Complex128Vector = require( '@stdlib/ndarray/vector/complex128' );
+
+var x = new Complex128Vector( [ 1.0, 2.0, 3.0, -1.0, 0.0, 1.0 ] );
+var y = new Complex128Vector( [ 2.0, 1.0, -1.0, 3.0, 4.0, 0.0 ] );
+var w = new Complex128Vector( 3 );
+
+zwxsy( [ x, y, w ] );
+// w => [ [ -1.0, 1.0 ], [ 4.0, -4.0 ], [ -4.0, 1.0 ] ]
+```
+
+The function has the following parameters:
+
+- **arrays**: array-like object containing the following ndarrays:
+
+ - first one-dimensional input ndarray.
+ - second one-dimensional input ndarray.
+ - a one-dimensional output ndarray.
+
+
+
+
+
+
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var discreteUniform = require( '@stdlib/random/array/discrete-uniform' );
+var Complex128Vector = require( '@stdlib/ndarray/vector/complex128' );
+var ndarray2array = require( '@stdlib/ndarray/to-array' );
+var zwxsy = require( '@stdlib/blas/ext/base/ndarray/zwxsy' );
+
+var opts = {
+ 'dtype': 'float64'
+};
+
+var x = new Complex128Vector( discreteUniform( 20, -100, 100, opts ) );
+console.log( ndarray2array( x ) );
+
+var y = new Complex128Vector( discreteUniform( 20, -100, 100, opts ) );
+console.log( ndarray2array( y ) );
+
+var w = new Complex128Vector( 10 );
+
+zwxsy( [ x, y, w ] );
+console.log( ndarray2array( w ) );
+```
