group-onsemi	0:098463de4c5d	196	* The functions operate on matrix data structures. For example,
group-onsemi	0:098463de4c5d	197	* the type
group-onsemi	0:098463de4c5d	198	* definition for the floating-point matrix structure is shown
group-onsemi	0:098463de4c5d	199	* below:
group-onsemi	0:098463de4c5d	200	* <pre>
group-onsemi	0:098463de4c5d	201	* typedef struct
group-onsemi	0:098463de4c5d	202	* {

group-onsemi	0:098463de4c5d	209	*
group-onsemi	0:098463de4c5d	210	* The structure specifies the size of the matrix and then points to

group-onsemi	0:098463de4c5d	225	* \par
group-onsemi	0:098463de4c5d	226	* Use of the initialization function is optional. However, if initialization function is used
group-onsemi	0:098463de4c5d	227	* then the instance structure cannot be placed into a const data section.
group-onsemi	0:098463de4c5d	228	* To place the instance structure in a const data

group-onsemi	0:098463de4c5d	230	* <pre>
group-onsemi	0:098463de4c5d	231	* <code>arm_matrix_instance_f32 S = {nRows, nColumns, pData};</code>
group-onsemi	0:098463de4c5d	232	* <code>arm_matrix_instance_q31 S = {nRows, nColumns, pData};</code>
group-onsemi	0:098463de4c5d	233	* <code>arm_matrix_instance_q15 S = {nRows, nColumns, pData};</code>
group-onsemi	0:098463de4c5d	234	* </pre>
group-onsemi	0:098463de4c5d	235	* where <code>nRows</code> specifies the number of rows, <code>nColumns</code>
group-onsemi	0:098463de4c5d	236	* specifies the number of columns, and <code>pData</code> points to the

group-onsemi	0:098463de4c5d	239	* \par Size Checking
group-onsemi	0:098463de4c5d	240	* By default all of the matrix functions perform size checking on the input and
group-onsemi	0:098463de4c5d	241	* output matrices. For example, the matrix addition function verifies that the
group-onsemi	0:098463de4c5d	242	* two input matrices and the output matrix all have the same number of rows and
group-onsemi	0:098463de4c5d	243	* columns. If the size check fails the functions return:
group-onsemi	0:098463de4c5d	244	* <pre>
group-onsemi	0:098463de4c5d	245	* ARM_MATH_SIZE_MISMATCH
group-onsemi	0:098463de4c5d	246	* </pre>
group-onsemi	0:098463de4c5d	247	* Otherwise the functions return
group-onsemi	0:098463de4c5d	248	* <pre>
group-onsemi	0:098463de4c5d	249	* ARM_MATH_SUCCESS
group-onsemi	0:098463de4c5d	250	* </pre>
group-onsemi	0:098463de4c5d	251	* There is some overhead associated with this matrix size checking.
group-onsemi	0:098463de4c5d	252	* The matrix size checking is enabled via the \#define
group-onsemi	0:098463de4c5d	253	* <pre>
group-onsemi	0:098463de4c5d	254	* ARM_MATH_MATRIX_CHECK
group-onsemi	0:098463de4c5d	255	* </pre>
group-onsemi	0:098463de4c5d	256	* within the library project settings. By default this macro is defined
group-onsemi	0:098463de4c5d	257	* and size checking is enabled. By changing the project settings and
group-onsemi	0:098463de4c5d	258	* undefining this macro size checking is eliminated and the functions
group-onsemi	0:098463de4c5d	259	* run a bit faster. With size checking disabled the functions always
group-onsemi	0:098463de4c5d	260	* return <code>ARM_MATH_SUCCESS</code>.

group-onsemi	0:098463de4c5d	7084	* Bilinear interpolation is an extension of linear interpolation applied to a two dimensional grid.

group-onsemi	0:098463de4c5d	7087	* Bilinear interpolation is equivalent to two step linear interpolation, first in the x-dimension and then in the y-dimension.
group-onsemi	0:098463de4c5d	7088	* Bilinear interpolation is often used in image processing to rescale images.
