Scales a single-precision complex floating-point vector by a single-precision complex floating-point constant and adds the result to a single-precision complex floating-point vector.

@param {PositiveInteger} N - number of indexed elements
@param {Complex64} alpha - scalar constant
@param {Complex64Array} x - first input array
@param {integer} strideX - `x` stride length
@param {Complex64Array} y - second input array
@param {integer} strideY - `y` stride length
@returns {Complex64Array} second input array

@example
var Complex64Array = require( '@stdlib/array/complex64' );
var Complex64 = require( '@stdlib/complex/float32/ctor' );

var x = new Complex64Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0 ] );
var y = new Complex64Array( [ 1.0, 1.0, 1.0, 1.0, 1.0, 1.0 ] );
var alpha = new Complex64( 2.0, 2.0 );

caxpy( 3, alpha, x, 1, y, 1 );
// y => <Complex64Array>[ -1.0, 7.0, -1.0, 15.0, -1.0, 23.0 ]
