The functions check to make sure that
pSrcA,pSrcB, andpDsthave the same number of rows and columns.Functions

Floating-point matrix addition.
- Parameters
pSrcA – [in] points to first input matrix structure
pSrcB – [in] points to second input matrix structure
pDst – [out] points to output matrix structure
- Returns
execution status
RISCV_MATH_SUCCESS : Operation successful
RISCV_MATH_SIZE_MISMATCH : Matrix size check failed
- RISCV_DSP_ATTRIBUTE riscv_status riscv_mat_add_f32 (const riscv_matrix_instance_f32 *pSrcA, const riscv_matrix_instance_f32 *pSrcB, riscv_matrix_instance_f32 *pDst)
Floating-point matrix addition.
- Parameters
pSrcA – [in] points to first input matrix structure
pSrcB – [in] points to second input matrix structure
pDst – [out] points to output matrix structure
- Returns
execution status
RISCV_MATH_SUCCESS : Operation successful

- RISCV_DSP_ATTRIBUTE riscv_status riscv_mat_add_q15 (const riscv_matrix_instance_q15 *pSrcA, const riscv_matrix_instance_q15 *pSrcB, riscv_matrix_instance_q15 *pDst)
Q15 matrix addition.
- Scaling and Overflow Behavior
The function uses saturating arithmetic. Results outside of the allowable Q15 range [0x8000 0x7FFF] are saturated.
- Parameters
pSrcA – [in] points to first input matrix structure
pSrcB – [in] points to second input matrix structure
pDst – [out] points to output matrix structure
- Returns
execution status

Q31 matrix addition.
- Scaling and Overflow Behavior
The function uses saturating arithmetic. Results outside of the allowable Q31 range [0x80000000 0x7FFFFFFF] are saturated.
- Parameters
pSrcA – [in] points to first input matrix structure
pSrcB – [in] points to second input matrix structure
pDst – [out] points to output matrix structure
- Returns
