CMSIS DSP Software Library: Matrix Addition Main Page Modules Data Structures Files Examples Functions Matrix Addition [Matrix Functions] Functions arm_status arm_mat_add_f32 (const arm_matrix_instance_f32 *pSrcA, const arm_matrix_instance_f32 *pSrcB, arm_matrix_instance_f32 *pDst) arm_status arm_mat_add_q31 (const arm_matrix_instance_q31 *pSrcA, const arm_matrix_instance_q31 *pSrcB, arm_matrix_instance_q31 *pDst) arm_status arm_mat_add_q15 (const arm_matrix_instance_q15 *pSrcA, const arm_matrix_instance_q15 *pSrcB, arm_matrix_instance_q15 *pDst) 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. Function Documentation arm_status arm_mat_add_f32 ( const arm_matrix_instance_f32 *  pSrcA, const arm_matrix_instance_f32 *  pSrcB, arm_matrix_instance_f32 *  pDst  ) Floating-point matrix addition. Parameters: [in]*pSrcApoints to the first input matrix structure [in]*pSrcBpoints to the second input matrix structure [out]*pDstpoints to output matrix structure Returns:The function returns either ARM_MATH_SIZE_MISMATCH or ARM_MATH_SUCCESS based on the outcome of size checking. Definition at line 65 of file arm_mat_add_f32.c. arm_status arm_mat_add_q31 ( const arm_matrix_instance_q31 *  pSrcA, const arm_matrix_instance_q31 *  pSrcB, arm_matrix_instance_q31 *  pDst  ) Q31 matrix addition. Parameters: [in]*pSrcApoints to the first input matrix structure [in]*pSrcBpoints to the second input matrix structure [out]*pDstpoints to output matrix structure Returns:The function returns either ARM_MATH_SIZE_MISMATCH or ARM_MATH_SUCCESS based on the outcome of size checking. Scaling and Overflow Behavior: The function uses saturating arithmetic. Results outside of the allowable Q31 range [0x80000000 0x7FFFFFFF] will be saturated.

Parameters: [in]*pSrcApoints to the first input matrix structure [in]*pSrcBpoints to the second input matrix structure [out]*pDstpoints to output matrix structure Returns:The function returns either ARM_MATH_SIZE_MISMATCH or ARM_MATH_SUCCESS based on the outcome of size checking.
