AnnaBridge	126:abea610beb85	200	* This set of functions provides basic matrix math operations.
AnnaBridge	126:abea610beb85	201	* The functions operate on matrix data structures. For example,
AnnaBridge	126:abea610beb85	202	* the type
AnnaBridge	126:abea610beb85	203	* definition for the floating-point matrix structure is shown
AnnaBridge	126:abea610beb85	204	* below:
AnnaBridge	126:abea610beb85	205	* <pre>
AnnaBridge	126:abea610beb85	206	* typedef struct
AnnaBridge	126:abea610beb85	207	* {
AnnaBridge	126:abea610beb85	208	* uint16_t numRows; // number of rows of the matrix.
AnnaBridge	126:abea610beb85	209	* uint16_t numCols; // number of columns of the matrix.
AnnaBridge	126:abea610beb85	210	* float32_t *pData; // points to the data of the matrix.
AnnaBridge	126:abea610beb85	211	* } arm_matrix_instance_f32;
AnnaBridge	126:abea610beb85	212	* </pre>
AnnaBridge	126:abea610beb85	213	* There are similar definitions for Q15 and Q31 data types.
AnnaBridge	126:abea610beb85	214	*
AnnaBridge	126:abea610beb85	215	* The structure specifies the size of the matrix and then points to
AnnaBridge	126:abea610beb85	216	* an array of data. The array is of size <code>numRows X numCols</code>
AnnaBridge	126:abea610beb85	217	* and the values are arranged in row order. That is, the
AnnaBridge	126:abea610beb85	218	* matrix element (i, j) is stored at:
AnnaBridge	126:abea610beb85	219	* <pre>
AnnaBridge	126:abea610beb85	220	* pData[i*numCols + j]
AnnaBridge	126:abea610beb85	221	* </pre>
AnnaBridge	126:abea610beb85	222	*
AnnaBridge	126:abea610beb85	223	* \par Init Functions
AnnaBridge	126:abea610beb85	224	* There is an associated initialization function for each type of matrix
AnnaBridge	126:abea610beb85	225	* data structure.
AnnaBridge	126:abea610beb85	226	* The initialization function sets the values of the internal structure fields.
AnnaBridge	126:abea610beb85	227	* Refer to the function <code>arm_mat_init_f32()</code>, <code>arm_mat_init_q31()</code>
AnnaBridge	126:abea610beb85	228	* and <code>arm_mat_init_q15()</code> for floating-point, Q31 and Q15 types, respectively.
AnnaBridge	126:abea610beb85	229	*
AnnaBridge	126:abea610beb85	230	* \par
AnnaBridge	126:abea610beb85	231	* Use of the initialization function is optional. However, if initialization function is used
AnnaBridge	126:abea610beb85	232	* then the instance structure cannot be placed into a const data section.
AnnaBridge	126:abea610beb85	233	* To place the instance structure in a const data
AnnaBridge	126:abea610beb85	234	* section, manually initialize the data structure. For example:
AnnaBridge	126:abea610beb85	235	* <pre>
AnnaBridge	126:abea610beb85	236	* <code>arm_matrix_instance_f32 S = {nRows, nColumns, pData};</code>
AnnaBridge	126:abea610beb85	237	* <code>arm_matrix_instance_q31 S = {nRows, nColumns, pData};</code>
AnnaBridge	126:abea610beb85	238	* <code>arm_matrix_instance_q15 S = {nRows, nColumns, pData};</code>
AnnaBridge	126:abea610beb85	239	* </pre>

AnnaBridge	126:abea610beb85	4838	* The proportional value determines the reaction to the current error,
AnnaBridge	126:abea610beb85	4839	* the integral value determines the reaction based on the sum of recent errors,

AnnaBridge	126:abea610beb85	4842	* \par Instance Structure
AnnaBridge	126:abea610beb85	4843	* The Gains A0, A1, A2 and state variables for a PID controller are stored together in an instance data structure.
AnnaBridge	126:abea610beb85	4844	* A separate instance structure must be defined for each PID Controller.
AnnaBridge	126:abea610beb85	4845	* There are separate instance structure declarations for each of the 3 supported data types.

AnnaBridge	126:abea610beb85	6769	*
AnnaBridge	126:abea610beb85	6770	* Bilinear interpolation is an extension of linear interpolation applied to a two dimensional grid.
AnnaBridge	126:abea610beb85	6771	* The underlying function <code>f(x, y)</code> is sampled on a regular grid and the interpolation process
AnnaBridge	126:abea610beb85	6772	* determines values between the grid points.
AnnaBridge	126:abea610beb85	6773	* Bilinear interpolation is equivalent to two step linear interpolation, first in the x-dimension and then in the y-dimension.
AnnaBridge	126:abea610beb85	6774	* Bilinear interpolation is often used in image processing to rescale images.
AnnaBridge	126:abea610beb85	6775	* The CMSIS DSP library provides bilinear interpolation functions for Q7, Q15, Q31, and floating-point data types.
AnnaBridge	126:abea610beb85	6776	*

AnnaBridge	126:abea610beb85	6778	* \par
AnnaBridge	126:abea610beb85	6779	* The instance structure used by the bilinear interpolation functions describes a two dimensional data table.
AnnaBridge	126:abea610beb85	6780	* For floating-point, the instance structure is defined as:
AnnaBridge	126:abea610beb85	6781	* <pre>
AnnaBridge	126:abea610beb85	6782	* typedef struct
AnnaBridge	126:abea610beb85	6783	* {
AnnaBridge	126:abea610beb85	6784	* uint16_t numRows;

AnnaBridge	126:abea610beb85	6790	* \par
AnnaBridge	126:abea610beb85	6791	* where <code>numRows</code> specifies the number of rows in the table;
AnnaBridge	126:abea610beb85	6792	* <code>numCols</code> specifies the number of columns in the table;
AnnaBridge	126:abea610beb85	6793	* and <code>pData</code> points to an array of size <code>numRows*numCols</code> values.
AnnaBridge	126:abea610beb85	6794	* The data table <code>pTable</code> is organized in row order and the supplied data values fall on integer indexes.
AnnaBridge	126:abea610beb85	6795	* That is, table element (x,y) is located at <code>pTable[x + y*numCols]</code> where x and y are integers.
AnnaBridge	126:abea610beb85	6796	*
AnnaBridge	126:abea610beb85	6797	* \par
AnnaBridge	126:abea610beb85	6798	* Let <code>(x, y)</code> specify the desired interpolation point. Then define:
AnnaBridge	126:abea610beb85	6799	* <pre>
AnnaBridge	126:abea610beb85	6800	* XF = floor(x)
AnnaBridge	126:abea610beb85	6801	* YF = floor(y)
AnnaBridge	126:abea610beb85	6802	* </pre>
AnnaBridge	126:abea610beb85	6803	* \par
AnnaBridge	126:abea610beb85	6804	* The interpolated output point is computed as:
AnnaBridge	126:abea610beb85	6805	* <pre>
AnnaBridge	126:abea610beb85	6806	* f(x, y) = f(XF, YF) * (1-(x-XF)) * (1-(y-YF))
AnnaBridge	126:abea610beb85	6807	* + f(XF+1, YF) * (x-XF)*(1-(y-YF))
AnnaBridge	126:abea610beb85	6808	* + f(XF, YF+1) * (1-(x-XF))*(y-YF)
AnnaBridge	126:abea610beb85	6809	* + f(XF+1, YF+1) * (x-XF)*(y-YF)
AnnaBridge	126:abea610beb85	6810	* </pre>
AnnaBridge	126:abea610beb85	6811	* Note that the coordinates (x, y) contain integer and fractional components.
AnnaBridge	126:abea610beb85	6812	* The integer components specify which portion of the table to use while the
AnnaBridge	126:abea610beb85	6813	* fractional components control the interpolation processor.
AnnaBridge	126:abea610beb85	6814	*
AnnaBridge	126:abea610beb85	6815	* \par
AnnaBridge	126:abea610beb85	6816	* if (x,y) are outside of the table boundary, Bilinear interpolation returns zero output.
