function assign( re1, im1, re2, im2, out, strideOut, offsetOut ) {
	out[ offsetOut ] = re1 + re2;
	out[ offsetOut+strideOut ] = im1 + im2;
	return out;
}
Adds two double-precision complex floating-point numbers and assigns results to a provided output array.

@param {number} re1 - real component of the first complex number
@param {number} im1 - imaginary component of the first complex number
@param {number} re2 - real component of the second complex number
@param {number} im2 - imaginary component of the second complex number
@param {Collection} out - output array
@param {integer} strideOut - stride length
@param {NonNegativeInteger} offsetOut - starting index
@returns {Collection} output array

@example
var Float64Array = require( '@stdlib/array/float64' );

var out = assign( 5.0, 3.0, -2.0, 1.0, new Float64Array( 2 ), 1, 0 );
// returns <Float64Array>[ 3.0, 4.0 ]
