-/**
- * @brief Q15 Complex matrix multiplication
- * @param[in] *pSrcA points to the first input complex matrix structure
- * @param[in] *pSrcB points to the second input complex matrix structure
- * @param[out] *pDst points to output complex matrix structure
- * @param[in] *pScratch points to the array for storing intermediate results
- * @return The function returns either
- * <code>ARM_MATH_SIZE_MISMATCH</code> or <code>ARM_MATH_SUCCESS</code> based on the outcome of size checking.
- *
- * \par Conditions for optimum performance
- * Input, output and state buffers should be aligned by 32-bit
- *
- * \par Restrictions
- * If the silicon does not support unaligned memory access enable the macro UNALIGNED_SUPPORT_DISABLE
- * In this case input, output, scratch buffers should be aligned by 32-bit
- *
- * @details
- * <b>Scaling and Overflow Behavior:</b>
- *
- * \par
- * The function is implemented using a 64-bit internal accumulator. The inputs to the
- * multiplications are in 1.15 format and multiplications yield a 2.30 result.
- * The 2.30 intermediate
- * results are accumulated in a 64-bit accumulator in 34.30 format. This approach
- * provides 33 guard bits and there is no risk of overflow. The 34.30 result is then
- * truncated to 34.15 format by discarding the low 15 bits and then saturated to
- * 1.15 format.
- *
- * \par
- * Refer to <code>arm_mat_mult_fast_q15()</code> for a faster but less precise version of this function.
