+# dcross
+
+> Compute the cross product of two double-precision floating-point input strided arrays and assign the results to an output strided array.
+
+
+
+
+
+
+
+## Usage
+
+```javascript
+var dcross = require( '@stdlib/blas/ext/base/dcross' );
+```
+
+#### dcross( x, strideX, y, strideY, z, strideZ )
+
+Computes the cross product of two double-precision floating-point input strided arrays and assigns the results to an output strided array.
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+
+var x = new Float64Array( [ 1.0, 2.0, 3.0 ] );
+var y = new Float64Array( [ 4.0, 5.0, 6.0 ] );
+var z = new Float64Array( [ 0.0, 0.0, 0.0 ] );
+
+dcross( x, 1, y, 1, z, 1 );
+// z => [ -3.0, 6.0, -3.0 ]
+```
+
+The function has the following parameters:
+
+- **x**: first input [`Float64Array`][@stdlib/array/float64]. Must contain `3` indexed elements.
+- **strideX**: stride length for `x`.
+- **y**: second input [`Float64Array`][@stdlib/array/float64]. Must contain `3` indexed elements.
+- **strideY**: stride length for `y`.
+- **z**: output [`Float64Array`][@stdlib/array/float64]. Must contain `3` indexed elements.
+- **strideZ**: stride length for `z`.
+
+The stride parameters determine which elements in the strided arrays are accessed at runtime. For example, to compute the cross product using every other element:
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+
+var x = new Float64Array( [ 1.0, 0.0, 2.0, 0.0, 3.0, 0.0 ] );
+var y = new Float64Array( [ 4.0, 0.0, 5.0, 0.0, 6.0, 0.0 ] );
+var z = new Float64Array( [ 0.0, 0.0, 0.0, 0.0, 0.0, 0.0 ] );
+
+dcross( x, 2, y, 2, z, 2 );
+// z => [ -3.0, 0.0, 6.0, 0.0, -3.0, 0.0 ]
+```
+
+Note that indexing is relative to the first index. To introduce an offset, use [`typed array`][mdn-typed-array] views.
+
+
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+
+// Initial arrays...
+var x0 = new Float64Array( [ 0.0, 1.0, 2.0, 3.0 ] );
+var y0 = new Float64Array( [ 0.0, 4.0, 5.0, 6.0 ] );
+var z0 = new Float64Array( [ 0.0, 0.0, 0.0, 0.0 ] );
+
+// Create offset views...
+var x1 = new Float64Array( x0.buffer, x0.BYTES_PER_ELEMENT*1 ); // start at 2nd element
+var y1 = new Float64Array( y0.buffer, y0.BYTES_PER_ELEMENT*1 ); // start at 2nd element
+var z1 = new Float64Array( z0.buffer, z0.BYTES_PER_ELEMENT*1 ); // start at 2nd element
+
+dcross( x1, 1, y1, 1, z1, 1 );
+// z0 => [ 0.0, -3.0, 6.0, -3.0 ]
+```
+
+#### dcross.ndarray( x, strideX, offsetX, y, strideY, offsetY, z, strideZ, offsetZ )
+
+Computes the cross product of two double-precision floating-point input strided arrays and assigns the results to an output strided array using alternative indexing semantics.
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+
+var x = new Float64Array( [ 1.0, 2.0, 3.0 ] );
+var y = new Float64Array( [ 4.0, 5.0, 6.0 ] );
+var z = new Float64Array( [ 0.0, 0.0, 0.0 ] );
+
+dcross.ndarray( x, 1, 0, y, 1, 0, z, 1, 0 );
+// z => [ -3.0, 6.0, -3.0 ]
+```
+
+The function has the following additional parameters:
+
+- **offsetX**: starting index for `x`.
+- **offsetY**: starting index for `y`.
+- **offsetZ**: starting index for `z`.
+
+While [`typed array`][mdn-typed-array] views mandate a view offset based on the underlying buffer, offset parameters support indexing semantics based on starting indices. For example:
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+
+var x = new Float64Array( [ 0.0, 1.0, 2.0, 3.0 ] );
+var y = new Float64Array( [ 0.0, 4.0, 5.0, 6.0 ] );
+var z = new Float64Array( [ 0.0, 0.0, 0.0, 0.0 ] );
+
+dcross.ndarray( x, 1, 1, y, 1, 1, z, 1, 1 );
+// z => [ 0.0, -3.0, 6.0, -3.0 ]
+```
+
+
+
+
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var discreteUniform = require( '@stdlib/random/array/discrete-uniform' );
+var Float64Array = require( '@stdlib/array/float64' );
+var dcross = require( '@stdlib/blas/ext/base/dcross' );
+
+var x = discreteUniform( 3, -100, 100, {
+ 'dtype': 'float64'
+});
+console.log( x );
+
+var y = discreteUniform( 3, -100, 100, {
+ 'dtype': 'float64'
+});
+console.log( y );
+
+var z = new Float64Array( 3 );
+
+dcross( x, 1, y, 1, z, 1 );
+console.log( z );
+```

+{{alias}}( x, strideX, y, strideY, z, strideZ )
+ Computes the cross product of two double-precision floating-point input

+
+ Parameters
+ ----------
