* Multiplies the Hadamard product of strided arrays `x` and `y` by a constant and adds the result to a strided array `z` multiplied by a constant.
*
* @param {PositiveInteger} N - number of indexed elements
* @param {number} alpha - first scalar constant
* @param {NumericArray} x - first input array
* @param {integer} strideX - `x` stride length
* @param {NumericArray} y - second input array
* @param {integer} strideY - `y` stride length
* @param {number} beta - second scalar constant
* @param {NumericArray} z - output array
* @param {integer} strideZ - `z` stride length
* @returns {NumericArray} output array

* @example
