Anna Bridge	180:96ed750bd169	200	* This set of functions provides basic matrix math operations.
Anna Bridge	180:96ed750bd169	201	* The functions operate on matrix data structures. For example,
Anna Bridge	180:96ed750bd169	202	* the type
Anna Bridge	180:96ed750bd169	203	* definition for the floating-point matrix structure is shown
Anna Bridge	180:96ed750bd169	204	* below:
Anna Bridge	180:96ed750bd169	205	* <pre>
Anna Bridge	180:96ed750bd169	206	* typedef struct
Anna Bridge	180:96ed750bd169	207	* {

Anna Bridge	180:96ed750bd169	213	* There are similar definitions for Q15 and Q31 data types.
Anna Bridge	180:96ed750bd169	214	*
Anna Bridge	180:96ed750bd169	215	* The structure specifies the size of the matrix and then points to
Anna Bridge	180:96ed750bd169	216	* an array of data. The array is of size <code>numRows X numCols</code>

Anna Bridge	180:96ed750bd169	224	* There is an associated initialization function for each type of matrix

Anna Bridge	180:96ed750bd169	226	* The initialization function sets the values of the internal structure fields.
Anna Bridge	180:96ed750bd169	227	* Refer to the function <code>arm_mat_init_f32()</code>, <code>arm_mat_init_q31()</code>
Anna Bridge	180:96ed750bd169	228	* and <code>arm_mat_init_q15()</code> for floating-point, Q31 and Q15 types, respectively.
Anna Bridge	180:96ed750bd169	229	*
Anna Bridge	180:96ed750bd169	230	* \par
Anna Bridge	180:96ed750bd169	231	* Use of the initialization function is optional. However, if initialization function is used
Anna Bridge	180:96ed750bd169	232	* then the instance structure cannot be placed into a const data section.
Anna Bridge	180:96ed750bd169	233	* To place the instance structure in a const data
Anna Bridge	180:96ed750bd169	234	* section, manually initialize the data structure. For example:
Anna Bridge	180:96ed750bd169	235	* <pre>
Anna Bridge	180:96ed750bd169	236	* <code>arm_matrix_instance_f32 S = {nRows, nColumns, pData};</code>
Anna Bridge	180:96ed750bd169	237	* <code>arm_matrix_instance_q31 S = {nRows, nColumns, pData};</code>
Anna Bridge	180:96ed750bd169	238	* <code>arm_matrix_instance_q15 S = {nRows, nColumns, pData};</code>
Anna Bridge	180:96ed750bd169	239	* </pre>
Anna Bridge	180:96ed750bd169	240	* where <code>nRows</code> specifies the number of rows, <code>nColumns</code>
Anna Bridge	180:96ed750bd169	241	* specifies the number of columns, and <code>pData</code> points to the
Anna Bridge	180:96ed750bd169	242	* data array.
Anna Bridge	180:96ed750bd169	243	*
Anna Bridge	180:96ed750bd169	244	* \par Size Checking
Anna Bridge	180:96ed750bd169	245	* By default all of the matrix functions perform size checking on the input and
Anna Bridge	180:96ed750bd169	246	* output matrices. For example, the matrix addition function verifies that the
Anna Bridge	180:96ed750bd169	247	* two input matrices and the output matrix all have the same number of rows and
Anna Bridge	180:96ed750bd169	248	* columns. If the size check fails the functions return:
Anna Bridge	180:96ed750bd169	249	* <pre>
Anna Bridge	180:96ed750bd169	250	* ARM_MATH_SIZE_MISMATCH
Anna Bridge	180:96ed750bd169	251	* </pre>
Anna Bridge	180:96ed750bd169	252	* Otherwise the functions return
Anna Bridge	180:96ed750bd169	253	* <pre>
Anna Bridge	180:96ed750bd169	254	* ARM_MATH_SUCCESS
Anna Bridge	180:96ed750bd169	255	* </pre>
Anna Bridge	180:96ed750bd169	256	* There is some overhead associated with this matrix size checking.
Anna Bridge	180:96ed750bd169	257	* The matrix size checking is enabled via the \#define
Anna Bridge	180:96ed750bd169	258	* <pre>
Anna Bridge	180:96ed750bd169	259	* ARM_MATH_MATRIX_CHECK
Anna Bridge	180:96ed750bd169	260	* </pre>
Anna Bridge	180:96ed750bd169	261	* within the library project settings. By default this macro is defined
Anna Bridge	180:96ed750bd169	262	* and size checking is enabled. By changing the project settings and
Anna Bridge	180:96ed750bd169	263	* undefining this macro size checking is eliminated and the functions
Anna Bridge	180:96ed750bd169	264	* run a bit faster. With size checking disabled the functions always
Anna Bridge	180:96ed750bd169	265	* return <code>ARM_MATH_SUCCESS</code>.

Anna Bridge	180:96ed750bd169	6703	* Bilinear interpolation is an extension of linear interpolation applied to a two dimensional grid.
Anna Bridge	180:96ed750bd169	6704	* The underlying function <code>f(x, y)</code> is sampled on a regular grid and the interpolation process
Anna Bridge	180:96ed750bd169	6705	* determines values between the grid points.
Anna Bridge	180:96ed750bd169	6706	* Bilinear interpolation is equivalent to two step linear interpolation, first in the x-dimension and then in the y-dimension.
Anna Bridge	180:96ed750bd169	6707	* Bilinear interpolation is often used in image processing to rescale images.
Anna Bridge	180:96ed750bd169	6708	* The CMSIS DSP library provides bilinear interpolation functions for Q7, Q15, Q31, and floating-point data types.
