Detailed Description
Adds two matrices.
Addition of two 3 x 3 matrices
The functions check to make sure that pSrcA, pSrcB, and pDst have the same number of rows and columns.

| ) |
Floating-point matrix addition.
- Parameters:
-
[in] *pSrcA points to the first input matrix structure [in] *pSrcB points to the second input matrix structure [out] *pDst points to output matrix structure
- Returns:
- The function returns either
ARM_MATH_SIZE_MISMATCHorARM_MATH_SUCCESSbased on the outcome of size checking.

| ) |
Q15 matrix addition.
- Parameters:
-
[in] *pSrcA points to the first input matrix structure [in] *pSrcB points to the second input matrix structure [out] *pDst points to output matrix structure
- Returns:
- The function returns either
ARM_MATH_SIZE_MISMATCHorARM_MATH_SUCCESSbased on the outcome of size checking.
Scaling and Overflow Behavior:
- The function uses saturating arithmetic. Results outside of the allowable Q15 range [0x8000 0x7FFF] will be saturated.

Q31 matrix addition.
- Parameters:
-
[in] *pSrcA points to the first input matrix structure [in] *pSrcB points to the second input matrix structure [out] *pDst points to output matrix structure
