AnnaBridge	126:abea610beb85	198	* definition for the floating-point matrix structure is shown
AnnaBridge	126:abea610beb85	199	* below:
AnnaBridge	126:abea610beb85	200	* <pre>
AnnaBridge	126:abea610beb85	201	* typedef struct
AnnaBridge	126:abea610beb85	202	* {

AnnaBridge	126:abea610beb85	207	* </pre>
AnnaBridge	126:abea610beb85	208	* There are similar definitions for Q15 and Q31 data types.
AnnaBridge	126:abea610beb85	209	*
AnnaBridge	126:abea610beb85	210	* The structure specifies the size of the matrix and then points to
AnnaBridge	126:abea610beb85	211	* an array of data. The array is of size <code>numRows X numCols</code>
AnnaBridge	126:abea610beb85	212	* and the values are arranged in row order. That is, the

AnnaBridge	126:abea610beb85	226	* Use of the initialization function is optional. However, if initialization function is used
AnnaBridge	126:abea610beb85	227	* then the instance structure cannot be placed into a const data section.
AnnaBridge	126:abea610beb85	228	* To place the instance structure in a const data
AnnaBridge	126:abea610beb85	229	* section, manually initialize the data structure. For example:
AnnaBridge	126:abea610beb85	230	* <pre>
AnnaBridge	126:abea610beb85	231	* <code>arm_matrix_instance_f32 S = {nRows, nColumns, pData};</code>
AnnaBridge	126:abea610beb85	232	* <code>arm_matrix_instance_q31 S = {nRows, nColumns, pData};</code>
AnnaBridge	126:abea610beb85	233	* <code>arm_matrix_instance_q15 S = {nRows, nColumns, pData};</code>
AnnaBridge	126:abea610beb85	234	* </pre>
AnnaBridge	126:abea610beb85	235	* where <code>nRows</code> specifies the number of rows, <code>nColumns</code>
AnnaBridge	126:abea610beb85	236	* specifies the number of columns, and <code>pData</code> points to the
AnnaBridge	126:abea610beb85	237	* data array.

AnnaBridge	126:abea610beb85	239	* \par Size Checking
AnnaBridge	126:abea610beb85	240	* By default all of the matrix functions perform size checking on the input and
AnnaBridge	126:abea610beb85	241	* output matrices. For example, the matrix addition function verifies that the
AnnaBridge	126:abea610beb85	242	* two input matrices and the output matrix all have the same number of rows and
AnnaBridge	126:abea610beb85	243	* columns. If the size check fails the functions return:
AnnaBridge	126:abea610beb85	244	* <pre>
AnnaBridge	126:abea610beb85	245	* ARM_MATH_SIZE_MISMATCH
AnnaBridge	126:abea610beb85	246	* </pre>
AnnaBridge	126:abea610beb85	247	* Otherwise the functions return
AnnaBridge	126:abea610beb85	248	* <pre>
AnnaBridge	126:abea610beb85	249	* ARM_MATH_SUCCESS
AnnaBridge	126:abea610beb85	250	* </pre>
AnnaBridge	126:abea610beb85	251	* There is some overhead associated with this matrix size checking.
AnnaBridge	126:abea610beb85	252	* The matrix size checking is enabled via the \#define
AnnaBridge	126:abea610beb85	253	* <pre>
AnnaBridge	126:abea610beb85	254	* ARM_MATH_MATRIX_CHECK
AnnaBridge	126:abea610beb85	255	* </pre>
AnnaBridge	126:abea610beb85	256	* within the library project settings. By default this macro is defined
AnnaBridge	126:abea610beb85	257	* and size checking is enabled. By changing the project settings and
AnnaBridge	126:abea610beb85	258	* undefining this macro size checking is eliminated and the functions
AnnaBridge	126:abea610beb85	259	* run a bit faster. With size checking disabled the functions always
AnnaBridge	126:abea610beb85	260	* return <code>ARM_MATH_SUCCESS</code>.

AnnaBridge	126:abea610beb85	5033	* loop mechanism widely used in industrial control systems.
AnnaBridge	126:abea610beb85	5034	* A PID controller is the most commonly used type of feedback controller.

AnnaBridge	126:abea610beb85	5036	* This set of functions implements (PID) controllers
AnnaBridge	126:abea610beb85	5037	* for Q15, Q31, and floating-point data types. The functions operate on a single sample
AnnaBridge	126:abea610beb85	5038	* of data and each call to the function returns a single processed value.

AnnaBridge	126:abea610beb85	5044	* y[n] = y[n-1] + A0 * x[n] + A1 * x[n-1] + A2 * x[n-2]

AnnaBridge	126:abea610beb85	5056	* The PID controller calculates an "error" value as the difference between
AnnaBridge	126:abea610beb85	5057	* the measured output and the reference input.
AnnaBridge	126:abea610beb85	5058	* The controller attempts to minimize the error by adjusting the process control inputs.
AnnaBridge	126:abea610beb85	5059	* The proportional value determines the reaction to the current error,
AnnaBridge	126:abea610beb85	5060	* the integral value determines the reaction based on the sum of recent errors,
AnnaBridge	126:abea610beb85	5061	* and the derivative value determines the reaction based on the rate at which the error has been changing.
AnnaBridge	126:abea610beb85	5062	*
AnnaBridge	126:abea610beb85	5063	* \par Instance Structure
AnnaBridge	126:abea610beb85	5064	* The Gains A0, A1, A2 and state variables for a PID controller are stored together in an instance data structure.
AnnaBridge	126:abea610beb85	5065	* A separate instance structure must be defined for each PID Controller.
AnnaBridge	126:abea610beb85	5066	* There are separate instance structure declarations for each of the 3 supported data types.
AnnaBridge	126:abea610beb85	5067	*
AnnaBridge	126:abea610beb85	5068	* \par Reset Functions
AnnaBridge	126:abea610beb85	5069	* There is also an associated reset function for each data type which clears the state array.
AnnaBridge	126:abea610beb85	5070	*
AnnaBridge	126:abea610beb85	5071	* \par Initialization Functions
AnnaBridge	126:abea610beb85	5072	* There is also an associated initialization function for each data type.
AnnaBridge	126:abea610beb85	5073	* The initialization function performs the following operations:
AnnaBridge	126:abea610beb85	5074	* - Initializes the Gains A0, A1, A2 from Kp,Ki, Kd gains.
AnnaBridge	126:abea610beb85	5075	* - Zeros out the values in the state buffer.
AnnaBridge	126:abea610beb85	5076	*
AnnaBridge	126:abea610beb85	5077	* \par
AnnaBridge	126:abea610beb85	5078	* Instance structure cannot be placed into a const data section and it is recommended to use the initialization function.
AnnaBridge	126:abea610beb85	5079	*
AnnaBridge	126:abea610beb85	5080	* \par Fixed-Point Behavior
AnnaBridge	126:abea610beb85	5081	* Care must be taken when using the fixed-point versions of the PID Controller functions.
AnnaBridge	126:abea610beb85	5082	* In particular, the overflow and saturation behavior of the accumulator used in each function must be considered.

AnnaBridge	126:abea610beb85	7084	* Bilinear interpolation is an extension of linear interpolation applied to a two dimensional grid.
AnnaBridge	126:abea610beb85	7085	* The underlying function <code>f(x, y)</code> is sampled on a regular grid and the interpolation process
AnnaBridge	126:abea610beb85	7086	* determines values between the grid points.
AnnaBridge	126:abea610beb85	7087	* Bilinear interpolation is equivalent to two step linear interpolation, first in the x-dimension and then in the y-dimension.
AnnaBridge	126:abea610beb85	7088	* Bilinear interpolation is often used in image processing to rescale images.
AnnaBridge	126:abea610beb85	7089	* The CMSIS DSP library provides bilinear interpolation functions for Q7, Q15, Q31, and floating-point data types.
