- *
- * \par
- * The function is implemented using a 64-bit internal accumulator. The inputs to the

- * The 2.30 intermediate
- * results are accumulated in a 64-bit accumulator in 34.30 format. This approach
- * provides 33 guard bits and there is no risk of overflow. The 34.30 result is then
- * truncated to 34.15 format by discarding the low 15 bits and then saturated to
- * 1.15 format.
- *

- * Matrix Inverse can be solved using elementary row operations.
- *
- * Gauss-Jordan Method:
- *
- * 1. First combine the identity matrix and the input matrix separated by a bar to form an
- * augmented matrix as follows:
- * _ _ _ _
- * | a11 a12 | 1 0 | | X11 X12 |
- * | | | = | |
- * |_ a21 a22 | 0 1 _| |_ X21 X21 _|
- *
- * 2. In our implementation, pDst Matrix is used as identity matrix.
- *
- * 3. Begin with the first row. Let i = 1.
- *
- * 4. Check to see if the pivot for column i is the greatest of the column.
- * The pivot is the element of the main diagonal that is on the current row.
- * For instance, if working with row i, then the pivot element is aii.
- * If the pivot is not the most significant of the columns, exchange that row with a row
- * below it that does contain the most significant value in column i. If the most
- * significant value of the column is zero, then an inverse to that matrix does not exist.
- * The most significant value of the column is the absolute maximum.
- *
- * 5. Divide every element of row i by the pivot.
- *
- * 6. For every row below and row i, replace that row with the sum of that row and
- * a multiple of row i so that each new element in column i below row i is zero.
- *
- * 7. Move to the next row and column and repeat steps 2 through 5 until you have zeros
- * for every element below and above the main diagonal.
- *
- * 8. Now an identical matrix is formed to the left of the bar(input matrix, pSrc).
- * Therefore, the matrix to the right of the bar is our solution(pDst matrix, pDst).

- * For instance, if working with row i, then the pivot element is aii.
- * If the pivot is zero, exchange that row with a row below it that does not
- * contain a zero in column i. If this is not possible, then an inverse
- * to that matrix does not exist.
- *
- * 5. Divide every element of row i by the pivot.

- * 6. For every row below and row i, replace that row with the sum of that row and

- * @defgroup MatrixInv Matrix Inverse
- *
- * Computes the inverse of a matrix.
- *
- * The inverse is defined only if the input matrix is square and non-singular (the determinant
- * is non-zero). The function checks that the input and output matrices are square and of the
- * same size.
- *
- * Matrix inversion is numerically sensitive and the CMSIS DSP library only supports matrix
- * inversion of floating-point matrices.
- *
- * \par Algorithm
- * The Gauss-Jordan method is used to find the inverse.
- * The algorithm performs a sequence of elementary row-operations until it
- * reduces the input matrix to an identity matrix. Applying the same sequence
- * of elementary row-operations to an identity matrix yields the inverse matrix.
- * If the input matrix is singular, then the algorithm terminates and returns error status
- * <code>ARM_MATH_SINGULAR</code>.

- * Matrix Inverse can be solved using elementary row operations.
- *
- * Gauss-Jordan Method:
- *
- * 1. First combine the identity matrix and the input matrix separated by a bar to form an
- * augmented matrix as follows:
- * _ _ _ _ _ _ _ _
- * | | a11 a12 | | | 1 0 | | | X11 X12 |
- * | | | | | | | = | |
- * |_ |_ a21 a22 _| | |_0 1 _| _| |_ X21 X21 _|
- *
- * 2. In our implementation, pDst Matrix is used as identity matrix.
- *
- * 3. Begin with the first row. Let i = 1.
- *
- * 4. Check to see if the pivot for row i is zero.
- * The pivot is the element of the main diagonal that is on the current row.
- * For instance, if working with row i, then the pivot element is aii.
- * If the pivot is zero, exchange that row with a row below it that does not
- * contain a zero in column i. If this is not possible, then an inverse
- * to that matrix does not exist.
- *
- * 5. Divide every element of row i by the pivot.
- *
- * 6. For every row below and row i, replace that row with the sum of that row and
- * a multiple of row i so that each new element in column i below row i is zero.
- *
- * 7. Move to the next row and column and repeat steps 2 through 5 until you have zeros
- * for every element below and above the main diagonal.
- *
- * 8. Now an identical matrix is formed to the left of the bar(input matrix, src).
- * Therefore, the matrix to the right of the bar is our solution(dst matrix, dst).

- * <b>Scaling and Overflow Behavior:</b>
- *
- * \par
- * The difference between the function arm_mat_mult_q15() and this fast variant is that
- * the fast variant use a 32-bit rather than a 64-bit accumulator.
- * The result of each 1.15 x 1.15 multiplication is truncated to
- * 2.30 format. These intermediate results are accumulated in a 32-bit register in 2.30
- * format. Finally, the accumulator is saturated and converted to a 1.15 result.
- *
- * \par
- * The fast version has the same overflow behavior as the standard version but provides
- * less precision since it discards the low 16 bits of each multiplication result.
- * In order to avoid overflows completely the input signals must be scaled down.
- * Scale down one of the input matrices by log2(numColsA) bits to
- * avoid overflows, as a total of numColsA additions are computed internally for each
- * output element.
- *
- * \par
- * See <code>arm_mat_mult_q15()</code> for a slower implementation of this function
- * which uses 64-bit accumulation to provide higher precision.

- * @brief Q31 matrix multiplication (fast variant) for Cortex-M3 and Cortex-M4
- * @param[in] *pSrcA points to the first input matrix structure
- * @param[in] *pSrcB points to the second input matrix structure
- * @param[out] *pDst points to output matrix structure
- * @return The function returns either
- * <code>ARM_MATH_SIZE_MISMATCH</code> or <code>ARM_MATH_SUCCESS</code> based on the outcome of size checking.
- *
- * @details
- * <b>Scaling and Overflow Behavior:</b>
- *
- * \par
- * The difference between the function arm_mat_mult_q31() and this fast variant is that
- * the fast variant use a 32-bit rather than a 64-bit accumulator.
- * The result of each 1.31 x 1.31 multiplication is truncated to
- * 2.30 format. These intermediate results are accumulated in a 32-bit register in 2.30
- * format. Finally, the accumulator is saturated and converted to a 1.31 result.
- *
- * \par
- * The fast version has the same overflow behavior as the standard version but provides
- * less precision since it discards the low 32 bits of each multiplication result.
- * In order to avoid overflows completely the input signals must be scaled down.
- * Scale down one of the input matrices by log2(numColsA) bits to
- * avoid overflows, as a total of numColsA additions are computed internally for each
- * output element.
- *
- * \par
- * See <code>arm_mat_mult_q31()</code> for a slower implementation of this function
- * which uses 64-bit accumulation to provide higher precision.

- * <b>Scaling and Overflow Behavior:</b>
- *
- * \par
- * The function is implemented using a 64-bit internal accumulator. The inputs to the
- * multiplications are in 1.15 format and multiplications yield a 2.30 result.
- * The 2.30 intermediate
- * results are accumulated in a 64-bit accumulator in 34.30 format. This approach
- * provides 33 guard bits and there is no risk of overflow. The 34.30 result is then
- * truncated to 34.15 format by discarding the low 15 bits and then saturated to
- * 1.15 format.
- *
- * \par
- * Refer to <code>arm_mat_mult_fast_q15()</code> for a faster but less precise version of this function for Cortex-M3 and Cortex-M4.

- *
- * \par
- * The function is implemented using an internal 64-bit accumulator.
- * The accumulator has a 2.62 format and maintains full precision of the intermediate
- * multiplication results but provides only a single guard bit. There is no saturation
- * on intermediate additions. Thus, if the accumulator overflows it wraps around and
- * distorts the result. The input signals should be scaled down to avoid intermediate
- * overflows. The input is thus scaled down by log2(numColsA) bits
- * to avoid overflows, as a total of numColsA additions are performed internally.
- * The 2.62 accumulator is right shifted by 31 bits and saturated to 1.31 format to yield the final result.
