- * Multiplying an <code>M x N</code> matrix with an <code>N x P</code> matrix results

- * in an <code>M x P</code> matrix.

- * When matrix size checking is enabled, the functions check: (1) that the inner dimensions of

- * matrix equals the outer dimensions of <code>pSrcA</code> and <code>pSrcB</code>.

- * @details

- * <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.

- * @param[in]       *pSrcA points to the first input complex matrix structure

- * @param[in]       *pSrcB points to the second input complex matrix structure

- * @param[out]      *pDst points to output complex matrix structure

- *

- * @details

- * <b>Scaling and Overflow Behavior:</b>

- *

- * \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.

- *

-	 * 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).

-	 *

-	 *	   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).

- * @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>.

-	 *	Gauss-Jordan Method:

-	 *

-	 *	   1. First combine the identity matrix and the input matrix separated by a bar to form an

-	 *        augmented matrix as follows:

-	 *				        _ 	      	       _         _	       _

-	 *					   |_ 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).

-	 * 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).

-/**

- * @brief Q15 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

- * @param[in]       *pState points to the array for storing intermediate results

- * @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_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.

- * The function is implemented using an internal 64-bit accumulator.

- * 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.

- *
