- * @brief Q15 matrix subtraction.
- * @param[in]       *pSrcA points to the first input matrix structure
- * @param[in]       *pSrcB points to the second input matrix structure
- * @param[out]      *pDst points to output matrix structure
- * @return     		The function returns either
- * <code>ARM_MATH_SIZE_MISMATCH</code> or <code>ARM_MATH_SUCCESS</code> based on the outcome of size checking.
- *
- * <b>Scaling and Overflow Behavior:</b>
- * \par
- * The function uses saturating arithmetic.
- * Results outside of the allowable Q15 range [0x8000 0x7FFF] will be saturated.
