- * @brief  Q15 complex dot product
- * @param  *pSrcA points to the first input vector
- * @param  *pSrcB points to the second input vector
- * @param  numSamples number of complex samples in each vector
- * @param  *realResult real part of the result returned here
- * @param  *imagResult imaginary part of the result returned here

- * <b>Scaling and Overflow Behavior:</b>
- * \par
- * The function is implemented using an internal 64-bit accumulator.
- * The intermediate 1.15 by 1.15 multiplications are performed with full precision and yield a 2.30 result.
- * These are accumulated in a 64-bit accumulator with 34.30 precision.
- * As a final step, the accumulators are converted to 8.24 format.
- * The return results <code>realResult</code> and <code>imagResult</code> are in 8.24 format.
