arm_status arm_mat_sub_f32 (const arm_matrix_instance_f32 *pSrcA, const arm_matrix_instance_f32 *pSrcB, arm_matrix_instance_f32 *pDst)
 Floating-point matrix subtraction.
 
arm_status arm_mat_sub_q15 (const arm_matrix_instance_q15 *pSrcA, const arm_matrix_instance_q15 *pSrcB, arm_matrix_instance_q15 *pDst)
 Q15 matrix subtraction.
 
arm_status arm_mat_sub_q31 (const arm_matrix_instance_q31 *pSrcA, const arm_matrix_instance_q31 *pSrcB, arm_matrix_instance_q31 *pDst)
 Q31 matrix subtraction.
 
-

Description

-

Subtract two matrices.

-
-MatrixSubtraction.gif -
-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.

arm_status arm_mat_sub_f32 (const arm_matrix_instance_f32 * pSrcA,
const arm_matrix_instance_f32 * pSrcB,
arm_matrix_instance_f32 * pDst 
)
-
-
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.

)
-
-
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 Q15 range [0x8000 0x7FFF] will be saturated.
