Usage

`javascript
var add = require( '@stdlib/complex-float64-base-add' );
`

#### add( z1, z2 )

Adds two double-precision complex floating-point numbers.

`javascript
var Complex128 = require( '@stdlib/complex-float64-ctor' );

var z = new Complex128( -1.5, 2.5 );

var v = add( z, z );
// returns [ -3.0, 5.0 ]
`

#### add.assign( re1, im1, re2, im2, out, strideOut, offsetOut )

Adds two 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 = add.assign( 5.0, 3.0, -2.0, 1.0, out, 1, 0 );
// returns [ 3.0, 4.0 ]

var bool = ( out === v );
// returns true
`

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.
- out: output array.
- strideOut: stride length for out.
- offsetOut: starting index for out.

#### add.strided( z1, sz1, oz1, z2, sz2, oz2, out, so, oo )

Adds two 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 out = new Float64Array( 2 );

var v = add.strided( z1, 1, 0, z2, 1, 0, out, 1, 0 );
// returns [ 3.0, 4.0 ]

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.
- out: output array.
- so: stride length for out.
- oo: starting index for out.
