Subtract two matrices.
Subraction 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.
- 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
- execution status
- 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
- execution status
- 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
- execution status
- 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
- execution status
- Scaling and Overflow Behavior
- The function uses saturating arithmetic. Results outside of the allowable Q15 range [0x8000 0x7FFF] are saturated.
