AnnaBridge	153:b484a57bc302	231	* Use of the initialization function is optional. However, if initialization function is used
AnnaBridge	153:b484a57bc302	232	* then the instance structure cannot be placed into a const data section.
AnnaBridge	153:b484a57bc302	233	* To place the instance structure in a const data
AnnaBridge	153:b484a57bc302	234	* section, manually initialize the data structure. For example:
AnnaBridge	153:b484a57bc302	235	* <pre>
AnnaBridge	153:b484a57bc302	236	* <code>arm_matrix_instance_f32 S = {nRows, nColumns, pData};</code>
AnnaBridge	153:b484a57bc302	237	* <code>arm_matrix_instance_q31 S = {nRows, nColumns, pData};</code>
AnnaBridge	153:b484a57bc302	238	* <code>arm_matrix_instance_q15 S = {nRows, nColumns, pData};</code>
AnnaBridge	153:b484a57bc302	239	* </pre>
AnnaBridge	153:b484a57bc302	240	* where <code>nRows</code> specifies the number of rows, <code>nColumns</code>
AnnaBridge	153:b484a57bc302	241	* specifies the number of columns, and <code>pData</code> points to the
AnnaBridge	153:b484a57bc302	242	* data array.
AnnaBridge	153:b484a57bc302	243	*
AnnaBridge	153:b484a57bc302	244	* \par Size Checking
AnnaBridge	153:b484a57bc302	245	* By default all of the matrix functions perform size checking on the input and
AnnaBridge	153:b484a57bc302	246	* output matrices. For example, the matrix addition function verifies that the
AnnaBridge	153:b484a57bc302	247	* two input matrices and the output matrix all have the same number of rows and
AnnaBridge	153:b484a57bc302	248	* columns. If the size check fails the functions return:
AnnaBridge	153:b484a57bc302	249	* <pre>
AnnaBridge	153:b484a57bc302	250	* ARM_MATH_SIZE_MISMATCH
AnnaBridge	153:b484a57bc302	251	* </pre>
AnnaBridge	153:b484a57bc302	252	* Otherwise the functions return
AnnaBridge	153:b484a57bc302	253	* <pre>
AnnaBridge	153:b484a57bc302	254	* ARM_MATH_SUCCESS
AnnaBridge	153:b484a57bc302	255	* </pre>
AnnaBridge	153:b484a57bc302	256	* There is some overhead associated with this matrix size checking.
AnnaBridge	153:b484a57bc302	257	* The matrix size checking is enabled via the \#define
AnnaBridge	153:b484a57bc302	258	* <pre>
AnnaBridge	153:b484a57bc302	259	* ARM_MATH_MATRIX_CHECK
AnnaBridge	153:b484a57bc302	260	* </pre>
AnnaBridge	153:b484a57bc302	261	* within the library project settings. By default this macro is defined
AnnaBridge	153:b484a57bc302	262	* and size checking is enabled. By changing the project settings and
AnnaBridge	153:b484a57bc302	263	* undefining this macro size checking is eliminated and the functions
AnnaBridge	153:b484a57bc302	264	* run a bit faster. With size checking disabled the functions always
AnnaBridge	153:b484a57bc302	265	* return <code>ARM_MATH_SUCCESS</code>.

AnnaBridge	153:b484a57bc302	4746	* A PID controller is the most commonly used type of feedback controller.

AnnaBridge	153:b484a57bc302	4749	* for Q15, Q31, and floating-point data types. The functions operate on a single sample

AnnaBridge	153:b484a57bc302	4768	* The PID controller calculates an "error" value as the difference between
AnnaBridge	153:b484a57bc302	4769	* the measured output and the reference input.
AnnaBridge	153:b484a57bc302	4770	* The controller attempts to minimize the error by adjusting the process control inputs.
AnnaBridge	153:b484a57bc302	4771	* The proportional value determines the reaction to the current error,
AnnaBridge	153:b484a57bc302	4772	* the integral value determines the reaction based on the sum of recent errors,
AnnaBridge	153:b484a57bc302	4773	* and the derivative value determines the reaction based on the rate at which the error has been changing.

AnnaBridge	153:b484a57bc302	4776	* The Gains A0, A1, A2 and state variables for a PID controller are stored together in an instance data structure.
AnnaBridge	153:b484a57bc302	4777	* A separate instance structure must be defined for each PID Controller.
AnnaBridge	153:b484a57bc302	4778	* There are separate instance structure declarations for each of the 3 supported data types.

AnnaBridge	153:b484a57bc302	4783	* \par Initialization Functions
AnnaBridge	153:b484a57bc302	4784	* There is also an associated initialization function for each data type.
AnnaBridge	153:b484a57bc302	4785	* The initialization function performs the following operations:
AnnaBridge	153:b484a57bc302	4786	* - Initializes the Gains A0, A1, A2 from Kp,Ki, Kd gains.
AnnaBridge	153:b484a57bc302	4787	* - Zeros out the values in the state buffer.

AnnaBridge	153:b484a57bc302	4792	* \par Fixed-Point Behavior
AnnaBridge	153:b484a57bc302	4793	* Care must be taken when using the fixed-point versions of the PID Controller functions.
AnnaBridge	153:b484a57bc302	4794	* In particular, the overflow and saturation behavior of the accumulator used in each function must be considered.

AnnaBridge	153:b484a57bc302	6703	* Bilinear interpolation is an extension of linear interpolation applied to a two dimensional grid.
AnnaBridge	153:b484a57bc302	6704	* The underlying function <code>f(x, y)</code> is sampled on a regular grid and the interpolation process
AnnaBridge	153:b484a57bc302	6705	* determines values between the grid points.
AnnaBridge	153:b484a57bc302	6706	* Bilinear interpolation is equivalent to two step linear interpolation, first in the x-dimension and then in the y-dimension.
AnnaBridge	153:b484a57bc302	6707	* Bilinear interpolation is often used in image processing to rescale images.
AnnaBridge	153:b484a57bc302	6708	* The CMSIS DSP library provides bilinear interpolation functions for Q7, Q15, Q31, and floating-point data types.
