switches	0:0e018d759a2a	44	* Introduction
switches	0:0e018d759a2a	45	* ------------
switches	0:0e018d759a2a	46	*
switches	0:0e018d759a2a	47	* This user manual describes the CMSIS DSP software library,

switches	0:0e018d759a2a	63	* 32-bit integer and 32-bit floating-point values.
switches	0:0e018d759a2a	64	*
switches	0:0e018d759a2a	65	* Using the Library
switches	0:0e018d759a2a	66	* ------------
switches	0:0e018d759a2a	67	*

switches	0:0e018d759a2a	195	* This set of functions provides basic matrix math operations.
switches	0:0e018d759a2a	196	* The functions operate on matrix data structures. For example,
switches	0:0e018d759a2a	197	* the type
switches	0:0e018d759a2a	198	* definition for the floating-point matrix structure is shown
switches	0:0e018d759a2a	199	* below:
switches	0:0e018d759a2a	200	* <pre>
switches	0:0e018d759a2a	201	* typedef struct
switches	0:0e018d759a2a	202	* {
switches	0:0e018d759a2a	203	* uint16_t numRows; // number of rows of the matrix.

switches	0:0e018d759a2a	205	* float32_t *pData; // points to the data of the matrix.
switches	0:0e018d759a2a	206	* } arm_matrix_instance_f32;
switches	0:0e018d759a2a	207	* </pre>
switches	0:0e018d759a2a	208	* There are similar definitions for Q15 and Q31 data types.
switches	0:0e018d759a2a	209	*
switches	0:0e018d759a2a	210	* The structure specifies the size of the matrix and then points to
switches	0:0e018d759a2a	211	* an array of data. The array is of size <code>numRows X numCols</code>
switches	0:0e018d759a2a	212	* and the values are arranged in row order. That is, the
switches	0:0e018d759a2a	213	* matrix element (i, j) is stored at:
switches	0:0e018d759a2a	214	* <pre>
switches	0:0e018d759a2a	215	* pData[i*numCols + j]
switches	0:0e018d759a2a	216	* </pre>
switches	0:0e018d759a2a	217	*
switches	0:0e018d759a2a	218	* \par Init Functions
switches	0:0e018d759a2a	219	* There is an associated initialization function for each type of matrix
switches	0:0e018d759a2a	220	* data structure.
switches	0:0e018d759a2a	221	* The initialization function sets the values of the internal structure fields.
switches	0:0e018d759a2a	222	* Refer to the function <code>arm_mat_init_f32()</code>, <code>arm_mat_init_q31()</code>
switches	0:0e018d759a2a	223	* and <code>arm_mat_init_q15()</code> for floating-point, Q31 and Q15 types, respectively.
switches	0:0e018d759a2a	224	*
switches	0:0e018d759a2a	225	* \par
switches	0:0e018d759a2a	226	* Use of the initialization function is optional. However, if initialization function is used
switches	0:0e018d759a2a	227	* then the instance structure cannot be placed into a const data section.
switches	0:0e018d759a2a	228	* To place the instance structure in a const data
switches	0:0e018d759a2a	229	* section, manually initialize the data structure. For example:
switches	0:0e018d759a2a	230	* <pre>
switches	0:0e018d759a2a	231	* <code>arm_matrix_instance_f32 S = {nRows, nColumns, pData};</code>
switches	0:0e018d759a2a	232	* <code>arm_matrix_instance_q31 S = {nRows, nColumns, pData};</code>
switches	0:0e018d759a2a	233	* <code>arm_matrix_instance_q15 S = {nRows, nColumns, pData};</code>
switches	0:0e018d759a2a	234	* </pre>
switches	0:0e018d759a2a	235	* where <code>nRows</code> specifies the number of rows, <code>nColumns</code>
switches	0:0e018d759a2a	236	* specifies the number of columns, and <code>pData</code> points to the
switches	0:0e018d759a2a	237	* data array.
switches	0:0e018d759a2a	238	*
switches	0:0e018d759a2a	239	* \par Size Checking
switches	0:0e018d759a2a	240	* By default all of the matrix functions perform size checking on the input and
switches	0:0e018d759a2a	241	* output matrices. For example, the matrix addition function verifies that the
switches	0:0e018d759a2a	242	* two input matrices and the output matrix all have the same number of rows and
switches	0:0e018d759a2a	243	* columns. If the size check fails the functions return:
switches	0:0e018d759a2a	244	* <pre>
