- * @brief Variance of the elements of a Q31 vector.

- * @param[in] blockSize length of the input vector
- * @param[out] *pResult variance value returned here
- * @return none.
- * @details
- * <b>Scaling and Overflow Behavior:</b>
- *
- *\par
- * The function is implemented using an internal 64-bit accumulator.
- * The input is represented in 1.31 format, which is then downshifted by 8 bits
- * which yields 1.23, and intermediate multiplication yields a 2.46 format.
- * The accumulator maintains full precision of the intermediate multiplication results,
- * but provides only a 16 guard bits.
- * There is no saturation on intermediate additions.
- * If the accumulator overflows it wraps around and distorts the result.
- * In order to avoid overflows completely the input signal must be scaled down by
- * log2(blockSize)-8 bits, as a total of blockSize additions are performed internally.
- * After division, internal variables should be Q18.46
- * Finally, the 18.46 accumulator is right shifted by 15 bits to yield a 1.31 format value.
