* Multiplies two double-precision complex floating-point numbers and assigns results to a provided output array.

* @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
