- * @brief Q31 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 1.31 by 1.31 multiplications are performed with 64-bit precision and then shifted to 16.48 format.
- * The internal real and imaginary accumulators are in 16.48 format and provide 15 guard bits.
- * Additions are nonsaturating and no overflow will occur as long as <code>numSamples</code> is less than 32768.
- * The return results <code>realResult</code> and <code>imagResult</code> are in 16.48 format.
- * Input down scaling is not required.
