NYX	0:85b3fd62ea1a	199	*
NYX	0:85b3fd62ea1a	200	* This set of functions provides basic matrix math operations.
NYX	0:85b3fd62ea1a	201	* The functions operate on matrix data structures. For example,
NYX	0:85b3fd62ea1a	202	* the type
NYX	0:85b3fd62ea1a	203	* definition for the floating-point matrix structure is shown
NYX	0:85b3fd62ea1a	204	* below:
NYX	0:85b3fd62ea1a	205	* <pre>
NYX	0:85b3fd62ea1a	206	* typedef struct
NYX	0:85b3fd62ea1a	207	* {
NYX	0:85b3fd62ea1a	208	* uint16_t numRows; // number of rows of the matrix.
NYX	0:85b3fd62ea1a	209	* uint16_t numCols; // number of columns of the matrix.
NYX	0:85b3fd62ea1a	210	* float32_t *pData; // points to the data of the matrix.
NYX	0:85b3fd62ea1a	211	* } arm_matrix_instance_f32;
NYX	0:85b3fd62ea1a	212	* </pre>
NYX	0:85b3fd62ea1a	213	* There are similar definitions for Q15 and Q31 data types.
NYX	0:85b3fd62ea1a	214	*
NYX	0:85b3fd62ea1a	215	* The structure specifies the size of the matrix and then points to
NYX	0:85b3fd62ea1a	216	* an array of data. The array is of size <code>numRows X numCols</code>
NYX	0:85b3fd62ea1a	217	* and the values are arranged in row order. That is, the
NYX	0:85b3fd62ea1a	218	* matrix element (i, j) is stored at:
NYX	0:85b3fd62ea1a	219	* <pre>
NYX	0:85b3fd62ea1a	220	* pData[i*numCols + j]
NYX	0:85b3fd62ea1a	221	* </pre>
NYX	0:85b3fd62ea1a	222	*
NYX	0:85b3fd62ea1a	223	* \par Init Functions
NYX	0:85b3fd62ea1a	224	* There is an associated initialization function for each type of matrix
NYX	0:85b3fd62ea1a	225	* data structure.
NYX	0:85b3fd62ea1a	226	* The initialization function sets the values of the internal structure fields.
NYX	0:85b3fd62ea1a	227	* Refer to the function <code>arm_mat_init_f32()</code>, <code>arm_mat_init_q31()</code>
NYX	0:85b3fd62ea1a	228	* and <code>arm_mat_init_q15()</code> for floating-point, Q31 and Q15 types, respectively.
NYX	0:85b3fd62ea1a	229	*
NYX	0:85b3fd62ea1a	230	* \par
NYX	0:85b3fd62ea1a	231	* Use of the initialization function is optional. However, if initialization function is used
NYX	0:85b3fd62ea1a	232	* then the instance structure cannot be placed into a const data section.
NYX	0:85b3fd62ea1a	233	* To place the instance structure in a const data
NYX	0:85b3fd62ea1a	234	* section, manually initialize the data structure. For example:
NYX	0:85b3fd62ea1a	235	* <pre>
NYX	0:85b3fd62ea1a	236	* <code>arm_matrix_instance_f32 S = {nRows, nColumns, pData};</code>
NYX	0:85b3fd62ea1a	237	* <code>arm_matrix_instance_q31 S = {nRows, nColumns, pData};</code>
NYX	0:85b3fd62ea1a	238	* <code>arm_matrix_instance_q15 S = {nRows, nColumns, pData};</code>
NYX	0:85b3fd62ea1a	239	* </pre>
NYX	0:85b3fd62ea1a	240	* where <code>nRows</code> specifies the number of rows, <code>nColumns</code>
NYX	0:85b3fd62ea1a	241	* specifies the number of columns, and <code>pData</code> points to the
NYX	0:85b3fd62ea1a	242	* data array.
NYX	0:85b3fd62ea1a	243	*
NYX	0:85b3fd62ea1a	244	* \par Size Checking
NYX	0:85b3fd62ea1a	245	* By default all of the matrix functions perform size checking on the input and
NYX	0:85b3fd62ea1a	246	* output matrices. For example, the matrix addition function verifies that the
NYX	0:85b3fd62ea1a	247	* two input matrices and the output matrix all have the same number of rows and
NYX	0:85b3fd62ea1a	248	* columns. If the size check fails the functions return:
NYX	0:85b3fd62ea1a	249	* <pre>
NYX	0:85b3fd62ea1a	250	* ARM_MATH_SIZE_MISMATCH
NYX	0:85b3fd62ea1a	251	* </pre>

NYX	0:85b3fd62ea1a	6770	* Bilinear interpolation is an extension of linear interpolation applied to a two dimensional grid.
NYX	0:85b3fd62ea1a	6771	* The underlying function <code>f(x, y)</code> is sampled on a regular grid and the interpolation process
NYX	0:85b3fd62ea1a	6772	* determines values between the grid points.
NYX	0:85b3fd62ea1a	6773	* Bilinear interpolation is equivalent to two step linear interpolation, first in the x-dimension and then in the y-dimension.
NYX	0:85b3fd62ea1a	6774	* Bilinear interpolation is often used in image processing to rescale images.
NYX	0:85b3fd62ea1a	6775	* The CMSIS DSP library provides bilinear interpolation functions for Q7, Q15, Q31, and floating-point data types.
