cactode	59:8aa304768360	234	* There is an associated initialization function for each type of matrix
cactode	59:8aa304768360	235	* data structure.
cactode	59:8aa304768360	236	* The initialization function sets the values of the internal structure fields.
cactode	59:8aa304768360	237	* Refer to \ref arm_mat_init_f32(), \ref arm_mat_init_q31() and \ref arm_mat_init_q15()
cactode	59:8aa304768360	238	* for floating-point, Q31 and Q15 types, respectively.

cactode	59:8aa304768360	240	* \par
cactode	59:8aa304768360	241	* Use of the initialization function is optional. However, if initialization function is used
cactode	59:8aa304768360	242	* then the instance structure cannot be placed into a const data section.
cactode	59:8aa304768360	243	* To place the instance structure in a const data
cactode	59:8aa304768360	244	* section, manually initialize the data structure. For example:
cactode	59:8aa304768360	245	* <pre>
cactode	59:8aa304768360	246	* <code>arm_matrix_instance_f32 S = {nRows, nColumns, pData};</code>
cactode	59:8aa304768360	247	* <code>arm_matrix_instance_q31 S = {nRows, nColumns, pData};</code>
cactode	59:8aa304768360	248	* <code>arm_matrix_instance_q15 S = {nRows, nColumns, pData};</code>
cactode	59:8aa304768360	249	* </pre>
cactode	59:8aa304768360	250	* where <code>nRows</code> specifies the number of rows, <code>nColumns</code>
cactode	59:8aa304768360	251	* specifies the number of columns, and <code>pData</code> points to the
cactode	59:8aa304768360	252	* data array.
cactode	59:8aa304768360	253	*
cactode	59:8aa304768360	254	* \par Size Checking
cactode	59:8aa304768360	255	* By default all of the matrix functions perform size checking on the input and
cactode	59:8aa304768360	256	* output matrices. For example, the matrix addition function verifies that the
cactode	59:8aa304768360	257	* two input matrices and the output matrix all have the same number of rows and
cactode	59:8aa304768360	258	* columns. If the size check fails the functions return:
cactode	59:8aa304768360	259	* <pre>
cactode	59:8aa304768360	260	* ARM_MATH_SIZE_MISMATCH
cactode	59:8aa304768360	261	* </pre>
cactode	59:8aa304768360	262	* Otherwise the functions return
cactode	59:8aa304768360	263	* <pre>
cactode	59:8aa304768360	264	* ARM_MATH_SUCCESS
cactode	59:8aa304768360	265	* </pre>
cactode	59:8aa304768360	266	* There is some overhead associated with this matrix size checking.
cactode	59:8aa304768360	267	* The matrix size checking is enabled via the \#define
cactode	59:8aa304768360	268	* <pre>
cactode	59:8aa304768360	269	* ARM_MATH_MATRIX_CHECK
cactode	59:8aa304768360	270	* </pre>
cactode	59:8aa304768360	271	* within the library project settings. By default this macro is defined
cactode	59:8aa304768360	272	* and size checking is enabled. By changing the project settings and
cactode	59:8aa304768360	273	* undefining this macro size checking is eliminated and the functions
cactode	59:8aa304768360	274	* run a bit faster. With size checking disabled the functions always
cactode	59:8aa304768360	275	* return <code>ARM_MATH_SUCCESS</code>.
