+## Usage
+
+```javascript
+var add4 = require( '@stdlib/complex/float64/base/add4' );
+```
+
+#### add4( z1, z2, z3, z4 )
+
+Computes the sum of four double-precision complex floating-point numbers.
+
+```javascript
+var Complex128 = require( '@stdlib/complex/float64/ctor' );
+
+var z = new Complex128( -1.5, 2.5 );
+
+var v = add4( z, z, z, z );
+// returns <Complex128>[ -7.5, 12.5 ]
+```
+
+The function supports the following parameters:
+
+-   **z1**: first complex number.
+-   **z2**: second complex number.
+-   **z3**: third complex number.
+-   **z4**: fourth complex number.
+
+#### add4.assign( re1, im1, re2, im2, re3, im3, re4, im4, out, strideOut, offsetOut )
+
+Computes the sum of four double-precision complex floating-point numbers and assigns results to a provided output array.
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+
+var out = new Float64Array( 2 );
+var v = add4.assign( 5.0, 3.0, -2.0, 1.0, 5.0, 3.0, 1.0, 4.0, out, 1, 0 );
+// returns <Float64Array>[ 9.0, 11.0 ]

+
+The function supports the following parameters:
+
+-   **re1**: real component of the first complex number.
+-   **im1**: imaginary component of the first complex number.
+-   **re2**: real component of the second complex number.
+-   **im2**: imaginary component of the second complex number.
+-   **re3**: real component of the third complex number.
+-   **im3**: imaginary component of the third complex number.
+-   **re4**: real component of the fourth complex number.
+-   **im4**: imaginary component of the fourth complex number.
+-   **out**: output array.
+-   **strideOut**: stride length for `out`.
+-   **offsetOut**: starting index for `out`.
+
+#### add4.strided( z1, sz1, oz1, z2, sz2, oz2, z3, sz3, oz3, z4, sz4, oz4, out, so, oo )
+
+Computes the sum of four double-precision complex floating-point numbers stored in real-valued strided array views and assigns results to a provided strided output array.
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+
+var z1 = new Float64Array( [ 5.0, 3.0 ] );
+var z2 = new Float64Array( [ -2.0, 1.0 ] );

+
+var v = add4.strided( z1, 1, 0, z2, 1, 0, z3, 1, 0, z4, 1, 0, out, 1, 0 );
+// returns <Float64Array>[ 9.0, 11.0 ]
+
+var bool = ( out === v );
+// returns true
+```
+
+The function supports the following parameters:
+
+-   **z1**: first complex number strided array view.
+-   **sz1**: stride length for `z1`.
+-   **oz1**: starting index for `z1`.
+-   **z2**: second complex number strided array view.
+-   **sz2**: stride length for `z2`.
+-   **oz2**: starting index for `z2`.
+-   **z3**: third complex number strided array view.
+-   **sz3**: stride length for `z3`.
+-   **oz3**: starting index for `z3`.
+-   **z4**: fourth complex number strided array view.
+-   **sz4**: stride length for `z4`.
+-   **oz4**: starting index for `z4`.
+-   **out**: output array.
