- * @brief Mean value of a Q31 vector.    
- * @param[in]       *pSrc points to the input vector    
- * @param[in]       blockSize length of the input vector    
- * @param[out]      *pResult mean value returned here    
- * @return none.    
- *    
- * @details    
- * <b>Scaling and Overflow Behavior:</b>    
- *\par    
- * The function is implemented using a 64-bit internal accumulator.    
- * The input is represented in 1.31 format and is accumulated in a 64-bit    
- * accumulator in 33.31 format.    
- * There is no risk of internal overflow with this approach, and the     
- * full precision of intermediate result is preserved.     
- * Finally, the accumulator is truncated to yield a result of 1.31 format.
