/**
* Multiplies a single-precision complex floating-point strided array `x` by a constant and adds the result to a single-precision complex floating-point strided array `y` multiplied by a constant using alternative indexing semantics.
*
* @param {PositiveInteger} N - number of indexed elements
* @param {Complex64} alpha - first scalar constant
* @param {Complex64Array} x - input array
* @param {integer} strideX - `x` stride length
* @param {NonNegativeInteger} offsetX - starting `x` index
* @param {Complex64} beta - second scalar constant
* @param {Complex64Array} y - output array
* @param {integer} strideY - `y` stride length
* @param {NonNegativeInteger} offsetY - starting `y` index
* @returns {Complex64Array} output 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, -1.0, 0.0, 1.0 ] );
