+# dwxsa
+
+> Subtract a scalar constant from each element in an input one-dimensional double-precision floating-point ndarray and assign the results to elements in a one-dimensional double-precision floating-point output ndarray.
+
+
+
+
+
+
+
+
+
+## Usage
+
+```javascript
+var dwxsa = require( '@stdlib/blas/ext/base/ndarray/dwxsa' );
+```
+
+#### dwxsa( arrays )
+
+Subtracts a scalar constant from each element in an input one-dimensional double-precision floating-point ndarray and assigns the results to elements in a one-dimensional double-precision floating-point output ndarray.
+
+```javascript
+var Float64Vector = require( '@stdlib/ndarray/vector/float64' );
+var scalar2ndarray = require( '@stdlib/ndarray/from-scalar' );
+
+var x = new Float64Vector( [ -2.0, 1.0, 3.0, -5.0, 4.0, 0.0, -1.0, -3.0 ] );
+var w = new Float64Vector( 8 );
+
+var alpha = scalar2ndarray( 5.0, {
+ 'dtype': 'float64'
+});
+
+dwxsa( [ x, w, alpha ] );
+// w => [ -7.0, -4.0, -2.0, -10.0, -1.0, -5.0, -6.0, -8.0 ]
+```
+
+The function has the following parameters:
+
+- **arrays**: array-like object containing the following ndarrays:
+
+ - a one-dimensional input ndarray.
+ - a one-dimensional output ndarray.
+ - a zero-dimensional ndarray containing the scalar constant to subtract.
+
+
+
+
+
+
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var discreteUniform = require( '@stdlib/random/discrete-uniform' );
+var scalar2ndarray = require( '@stdlib/ndarray/from-scalar' );
+var ndarray2array = require( '@stdlib/ndarray/to-array' );
+var ndarraylike2scalar = require( '@stdlib/ndarray/ndarraylike2scalar' );
+var dwxsa = require( '@stdlib/blas/ext/base/ndarray/dwxsa' );
+
+var opts = {
+ 'dtype': 'float64'
+};
+
+var x = discreteUniform( [ 10 ], -100, 100, opts );
+console.log( ndarray2array( x ) );
+
+var w = discreteUniform( [ 10 ], -100, 100, opts );
+console.log( ndarray2array( w ) );
+
+var alpha = scalar2ndarray( 5.0, opts );
+console.log( 'Alpha: %d', ndarraylike2scalar( alpha ) );
+
+dwxsa( [ x, w, alpha ] );
+console.log( ndarray2array( w ) );
