- * @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    
- * @return none.    
- *    
- * <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.
