MikamiUitOpen	4:c1beacfc42c7	44	* Introduction
MikamiUitOpen	4:c1beacfc42c7	45	* ------------
MikamiUitOpen	4:c1beacfc42c7	46	*
MikamiUitOpen	4:c1beacfc42c7	47	* This user manual describes the CMSIS DSP software library,

MikamiUitOpen	4:c1beacfc42c7	195	* This set of functions provides basic matrix math operations.
MikamiUitOpen	4:c1beacfc42c7	196	* The functions operate on matrix data structures. For example,
MikamiUitOpen	4:c1beacfc42c7	197	* the type
MikamiUitOpen	4:c1beacfc42c7	198	* definition for the floating-point matrix structure is shown
MikamiUitOpen	4:c1beacfc42c7	199	* below:
MikamiUitOpen	4:c1beacfc42c7	200	* <pre>
MikamiUitOpen	4:c1beacfc42c7	201	* typedef struct
MikamiUitOpen	4:c1beacfc42c7	202	* {
MikamiUitOpen	4:c1beacfc42c7	203	* uint16_t numRows; // number of rows of the matrix.
MikamiUitOpen	4:c1beacfc42c7	204	* uint16_t numCols; // number of columns of the matrix.
MikamiUitOpen	4:c1beacfc42c7	205	* float32_t *pData; // points to the data of the matrix.
MikamiUitOpen	4:c1beacfc42c7	206	* } arm_matrix_instance_f32;
MikamiUitOpen	4:c1beacfc42c7	207	* </pre>
MikamiUitOpen	4:c1beacfc42c7	208	* There are similar definitions for Q15 and Q31 data types.
MikamiUitOpen	4:c1beacfc42c7	209	*
MikamiUitOpen	4:c1beacfc42c7	210	* The structure specifies the size of the matrix and then points to
MikamiUitOpen	4:c1beacfc42c7	211	* an array of data. The array is of size <code>numRows X numCols</code>
MikamiUitOpen	4:c1beacfc42c7	212	* and the values are arranged in row order. That is, the
MikamiUitOpen	4:c1beacfc42c7	213	* matrix element (i, j) is stored at:
MikamiUitOpen	4:c1beacfc42c7	214	* <pre>
MikamiUitOpen	4:c1beacfc42c7	215	* pData[i*numCols + j]
MikamiUitOpen	4:c1beacfc42c7	216	* </pre>
MikamiUitOpen	4:c1beacfc42c7	217	*
MikamiUitOpen	4:c1beacfc42c7	218	* \par Init Functions
MikamiUitOpen	4:c1beacfc42c7	219	* There is an associated initialization function for each type of matrix
MikamiUitOpen	4:c1beacfc42c7	220	* data structure.
MikamiUitOpen	4:c1beacfc42c7	221	* The initialization function sets the values of the internal structure fields.
MikamiUitOpen	4:c1beacfc42c7	222	* Refer to the function <code>arm_mat_init_f32()</code>, <code>arm_mat_init_q31()</code>
MikamiUitOpen	4:c1beacfc42c7	223	* and <code>arm_mat_init_q15()</code> for floating-point, Q31 and Q15 types, respectively.
MikamiUitOpen	4:c1beacfc42c7	224	*
MikamiUitOpen	4:c1beacfc42c7	225	* \par
MikamiUitOpen	4:c1beacfc42c7	226	* Use of the initialization function is optional. However, if initialization function is used
MikamiUitOpen	4:c1beacfc42c7	227	* then the instance structure cannot be placed into a const data section.
MikamiUitOpen	4:c1beacfc42c7	228	* To place the instance structure in a const data
MikamiUitOpen	4:c1beacfc42c7	229	* section, manually initialize the data structure. For example:
MikamiUitOpen	4:c1beacfc42c7	230	* <pre>
MikamiUitOpen	4:c1beacfc42c7	231	* <code>arm_matrix_instance_f32 S = {nRows, nColumns, pData};</code>
MikamiUitOpen	4:c1beacfc42c7	232	* <code>arm_matrix_instance_q31 S = {nRows, nColumns, pData};</code>
MikamiUitOpen	4:c1beacfc42c7	233	* <code>arm_matrix_instance_q15 S = {nRows, nColumns, pData};</code>
MikamiUitOpen	4:c1beacfc42c7	234	* </pre>
MikamiUitOpen	4:c1beacfc42c7	235	* where <code>nRows</code> specifies the number of rows, <code>nColumns</code>
MikamiUitOpen	4:c1beacfc42c7	236	* specifies the number of columns, and <code>pData</code> points to the
MikamiUitOpen	4:c1beacfc42c7	237	* data array.
MikamiUitOpen	4:c1beacfc42c7	238	*
MikamiUitOpen	4:c1beacfc42c7	239	* \par Size Checking
MikamiUitOpen	4:c1beacfc42c7	240	* By default all of the matrix functions perform size checking on the input and
MikamiUitOpen	4:c1beacfc42c7	241	* output matrices. For example, the matrix addition function verifies that the
