+# gxsy
+
+> Subtract the elements of an output one-dimensional ndarray from the corresponding elements in an input one-dimensional ndarray and assign the results to the output ndarray.
+
+
+
+This BLAS extension implements the operation
+
+
+
+```math
+\mathbf{y} = \mathbf{x} - \mathbf{y}
+```
+
+
+
+This API is a specialized version of the package [`@stdlib/blas/ext/base/ndarray/gaxpby`][@stdlib/blas/ext/base/ndarray/gaxpby] with `α = 1` and `β = -1` and performs element-wise subtraction between two vectors.
+
+
+
+
+
+
+
+## Usage
+
+```javascript
+var gxsy = require( '@stdlib/blas/ext/base/ndarray/gxsy' );
+```
+
+#### gxsy( arrays )
+
+Subtracts the elements of an output one-dimensional ndarray from the corresponding elements in an input one-dimensional ndarray and assigns the results to the output ndarray.
+
+```javascript
+var vector = require( '@stdlib/ndarray/vector/ctor' );
+
+var x = vector( [ 1.0, 2.0, 3.0, 4.0, 5.0 ], 'generic' );
+var y = vector( [ 5.0, 4.0, 3.0, 2.0, 1.0 ], 'generic' );
+
+gxsy( [ x, y ] );
+// y => [ -4.0, -2.0, 0.0, 2.0, 4.0 ]
+```
+
+The function has the following parameters:
+
+- **arrays**: array-like object containing the following ndarrays:
+
+ - a one-dimensional input ndarray.
+ - a one-dimensional output ndarray.
+
+
+
+
+
+
+
+## Notes
+
+- The output ndarray is modified **in-place** (i.e., the output ndarray is **mutated**).
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var discreteUniform = require( '@stdlib/random/discrete-uniform' );
+var ndarray2array = require( '@stdlib/ndarray/to-array' );
+var gxsy = require( '@stdlib/blas/ext/base/ndarray/gxsy' );
+
+var opts = {
+ 'dtype': 'generic'
+};
+
+var x = discreteUniform( [ 10 ], -100, 100, opts );
+console.log( ndarray2array( x ) );
+
+var y = discreteUniform( [ 10 ], -100, 100, opts );
+console.log( ndarray2array( y ) );
+
+gxsy( [ x, y ] );
+console.log( ndarray2array( y ) );
+```
