Kojto	124:2241e3a39974	198	* definition for the floating-point matrix structure is shown
Kojto	124:2241e3a39974	199	* below:
Kojto	124:2241e3a39974	200	* <pre>
Kojto	124:2241e3a39974	201	* typedef struct
Kojto	124:2241e3a39974	202	* {
Kojto	124:2241e3a39974	203	* uint16_t numRows; // number of rows of the matrix.
Kojto	124:2241e3a39974	204	* uint16_t numCols; // number of columns of the matrix.
Kojto	124:2241e3a39974	205	* float32_t *pData; // points to the data of the matrix.
Kojto	124:2241e3a39974	206	* } arm_matrix_instance_f32;
Kojto	124:2241e3a39974	207	* </pre>
Kojto	124:2241e3a39974	208	* There are similar definitions for Q15 and Q31 data types.
Kojto	124:2241e3a39974	209	*
Kojto	124:2241e3a39974	210	* The structure specifies the size of the matrix and then points to
Kojto	124:2241e3a39974	211	* an array of data. The array is of size <code>numRows X numCols</code>
Kojto	124:2241e3a39974	212	* and the values are arranged in row order. That is, the
Kojto	124:2241e3a39974	213	* matrix element (i, j) is stored at:
Kojto	124:2241e3a39974	214	* <pre>
Kojto	124:2241e3a39974	215	* pData[i*numCols + j]
Kojto	124:2241e3a39974	216	* </pre>
Kojto	124:2241e3a39974	217	*
Kojto	124:2241e3a39974	218	* \par Init Functions
Kojto	124:2241e3a39974	219	* There is an associated initialization function for each type of matrix
Kojto	124:2241e3a39974	220	* data structure.
Kojto	124:2241e3a39974	221	* The initialization function sets the values of the internal structure fields.
Kojto	124:2241e3a39974	222	* Refer to the function <code>arm_mat_init_f32()</code>, <code>arm_mat_init_q31()</code>
Kojto	124:2241e3a39974	223	* and <code>arm_mat_init_q15()</code> for floating-point, Q31 and Q15 types, respectively.
Kojto	124:2241e3a39974	224	*
Kojto	124:2241e3a39974	225	* \par
Kojto	124:2241e3a39974	226	* Use of the initialization function is optional. However, if initialization function is used
Kojto	124:2241e3a39974	227	* then the instance structure cannot be placed into a const data section.
Kojto	124:2241e3a39974	228	* To place the instance structure in a const data
Kojto	124:2241e3a39974	229	* section, manually initialize the data structure. For example:
Kojto	124:2241e3a39974	230	* <pre>
Kojto	124:2241e3a39974	231	* <code>arm_matrix_instance_f32 S = {nRows, nColumns, pData};</code>
Kojto	124:2241e3a39974	232	* <code>arm_matrix_instance_q31 S = {nRows, nColumns, pData};</code>
Kojto	124:2241e3a39974	233	* <code>arm_matrix_instance_q15 S = {nRows, nColumns, pData};</code>
Kojto	124:2241e3a39974	234	* </pre>
Kojto	124:2241e3a39974	235	* where <code>nRows</code> specifies the number of rows, <code>nColumns</code>
Kojto	124:2241e3a39974	236	* specifies the number of columns, and <code>pData</code> points to the
Kojto	124:2241e3a39974	237	* data array.
Kojto	124:2241e3a39974	238	*
Kojto	124:2241e3a39974	239	* \par Size Checking
Kojto	124:2241e3a39974	240	* By default all of the matrix functions perform size checking on the input and
Kojto	124:2241e3a39974	241	* output matrices. For example, the matrix addition function verifies that the
Kojto	124:2241e3a39974	242	* two input matrices and the output matrix all have the same number of rows and
Kojto	124:2241e3a39974	243	* columns. If the size check fails the functions return:
Kojto	124:2241e3a39974	244	* <pre>
Kojto	124:2241e3a39974	245	* ARM_MATH_SIZE_MISMATCH
Kojto	124:2241e3a39974	246	* </pre>
Kojto	124:2241e3a39974	247	* Otherwise the functions return
Kojto	124:2241e3a39974	248	* <pre>
Kojto	124:2241e3a39974	249	* ARM_MATH_SUCCESS
Kojto	124:2241e3a39974	250	* </pre>
Kojto	124:2241e3a39974	251	* There is some overhead associated with this matrix size checking.
Kojto	124:2241e3a39974	252	* The matrix size checking is enabled via the \#define
Kojto	124:2241e3a39974	253	* <pre>
Kojto	124:2241e3a39974	254	* ARM_MATH_MATRIX_CHECK
Kojto	124:2241e3a39974	255	* </pre>
Kojto	124:2241e3a39974	256	* within the library project settings. By default this macro is defined
Kojto	124:2241e3a39974	257	* and size checking is enabled. By changing the project settings and
Kojto	124:2241e3a39974	258	* undefining this macro size checking is eliminated and the functions
Kojto	124:2241e3a39974	259	* run a bit faster. With size checking disabled the functions always
Kojto	124:2241e3a39974	260	* return <code>ARM_MATH_SUCCESS</code>.

Kojto	124:2241e3a39974	5081	* Care must be taken when using the fixed-point versions of the PID Controller functions.
Kojto	124:2241e3a39974	5082	* In particular, the overflow and saturation behavior of the accumulator used in each function must be considered.

Kojto	124:2241e3a39974	7084	* Bilinear interpolation is an extension of linear interpolation applied to a two dimensional grid.
Kojto	124:2241e3a39974	7085	* The underlying function <code>f(x, y)</code> is sampled on a regular grid and the interpolation process
Kojto	124:2241e3a39974	7086	* determines values between the grid points.
Kojto	124:2241e3a39974	7087	* Bilinear interpolation is equivalent to two step linear interpolation, first in the x-dimension and then in the y-dimension.
Kojto	124:2241e3a39974	7088	* Bilinear interpolation is often used in image processing to rescale images.
Kojto	124:2241e3a39974	7089	* The CMSIS DSP library provides bilinear interpolation functions for Q7, Q15, Q31, and floating-point data types.
