- *
- * A Proportional Integral Derivative (PID) controller is a generic feedback control
- * loop mechanism widely used in industrial control systems.
- * A PID controller is the most commonly used type of feedback controller.
- *
- * This set of functions implements (PID) controllers
- * for Q15, Q31, and floating-point data types. The functions operate on a single sample
- * of data and each call to the function returns a single processed value.
- * S points to an instance of the PID control data structure. in
- * is the input sample value. The functions return the output value.
- *
- * \par Algorithm:
- *
- * y[n] = y[n-1] + A0 * x[n] + A1 * x[n-1] + A2 * x[n-2]
- * A0 = Kp + Ki + Kd
- * A1 = (-Kp ) - (2 * Kd )
- * A2 = Kd
- *
- *
- * \par
- * where \c Kp is proportional constant, \c Ki is Integral constant and \c Kd is Derivative constant
- *
- * \par
- * \image html PID.gif "Proportional Integral Derivative Controller"
- *
- * \par
- * The PID controller calculates an "error" value as the difference between
- * the measured output and the reference input.
- * The controller attempts to minimize the error by adjusting the process control inputs.
- * The proportional value determines the reaction to the current error,
- * the integral value determines the reaction based on the sum of recent errors,
- * and the derivative value determines the reaction based on the rate at which the error has been changing.
- *
- * \par Instance Structure
- * The Gains A0, A1, A2 and state variables for a PID controller are stored together in an instance data structure.
- * A separate instance structure must be defined for each PID Controller.
- * There are separate instance structure declarations for each of the 3 supported data types.
- *
- * \par Reset Functions
- * There is also an associated reset function for each data type which clears the state array.
- *
- * \par Initialization Functions
- * There is also an associated initialization function for each data type.
- * The initialization function performs the following operations:
- * - Initializes the Gains A0, A1, A2 from Kp,Ki, Kd gains.
- * - Zeros out the values in the state buffer.
- *
- * \par
- * Instance structure cannot be placed into a const data section and it is recommended to use the initialization function.
- *
- * \par Fixed-Point Behavior
- * Care must be taken when using the fixed-point versions of the PID Controller functions.
- * In particular, the overflow and saturation behavior of the accumulator used in each function must be considered.
- * Refer to the function specific documentation below for usage guidelines.

- * @defgroup BilinearInterpolate Bilinear Interpolation
- *
- * Bilinear interpolation is an extension of linear interpolation applied to a two dimensional grid.
- * The underlying function f(x, y) is sampled on a regular grid and the interpolation process
- * determines values between the grid points.
- * Bilinear interpolation is equivalent to two step linear interpolation, first in the x-dimension and then in the y-dimension.
- * Bilinear interpolation is often used in image processing to rescale images.
- * The CMSIS DSP library provides bilinear interpolation functions for Q7, Q15, Q31, and floating-point data types.
- *
- * Algorithm
- * \par
- * The instance structure used by the bilinear interpolation functions describes a two dimensional data table.
- * For floating-point, the instance structure is defined as:
- *
- * typedef struct
- * {
- * uint16_t numRows;
- * uint16_t numCols;
- * float32_t *pData;
- * } arm_bilinear_interp_instance_f32;
- *
- *
- * \par
- * where numRows specifies the number of rows in the table;
- * numCols specifies the number of columns in the table;
- * and pData points to an array of size numRows*numCols values.
- * The data table pTable is organized in row order and the supplied data values fall on integer indexes.
- * That is, table element (x,y) is located at pTable[x + y*numCols] where x and y are integers.
- *
- * \par
- * Let (x, y) specify the desired interpolation point. Then define:
- *
- * XF = floor(x)
- * YF = floor(y)
- *
- * \par
- * The interpolated output point is computed as:
- *
- * f(x, y) = f(XF, YF) * (1-(x-XF)) * (1-(y-YF))
- * + f(XF+1, YF) * (x-XF)*(1-(y-YF))
- * + f(XF, YF+1) * (1-(x-XF))*(y-YF)
- * + f(XF+1, YF+1) * (x-XF)*(y-YF)
- *
- * Note that the coordinates (x, y) contain integer and fractional components.
- * The integer components specify which portion of the table to use while the
- * fractional components control the interpolation processor.
- *
- * \par
- * if (x,y) are outside of the table boundary, Bilinear interpolation returns zero output.

- by such Contributor that are necessarily infringed by their
- Contribution(s) alone or by combination of their Contribution(s)
- with the Work to which such Contribution(s) was submitted. If You
- institute patent litigation against any entity (including a
- cross-claim or counterclaim in a lawsuit) alleging that the Work
- or a Contribution incorporated within the Work constitutes direct
- or contributory patent infringement, then any patent licenses
- granted to You under this License for that Work shall terminate
- as of the date such litigation is filed.
-
- 4. Redistribution. You may reproduce and distribute copies of the
- Work or Derivative Works thereof in any medium, with or without

- of the following places: within a NOTICE text file distributed
- as part of the Derivative Works; within the Source form or
- documentation, if provided along with the Derivative Works; or,
- within a display generated by the Derivative Works, if and
- wherever such third-party notices normally appear. The contents
- of the NOTICE file are for informational purposes only and
- do not modify the License. You may add Your own attribution
- notices within Derivative Works that You distribute, alongside
- or as an addendum to the NOTICE text from the Work, provided
- that such additional attribution notices cannot be construed
- as modifying the License.
-
- You may add Your own copyright statement to Your modifications and
- may provide additional or different license terms and conditions
- for use, reproduction, or distribution of Your modifications, or
- for any such Derivative Works as a whole, provided Your use,
- reproduction, and distribution of the Work otherwise complies with
- the conditions stated in this License.
-
- 5. Submission of Contributions. Unless You explicitly state otherwise,
- any Contribution intentionally submitted for inclusion in the Work
- by You to the Licensor shall be under the terms and conditions of
- this License, without any additional terms or conditions.

- unless required by applicable law (such as deliberate and grossly
- negligent acts) or agreed to in writing, shall any Contributor be
- liable to You for damages, including any direct, indirect, special,
- incidental, or consequential damages of any character arising as a
- result of this License or out of the use or inability to use the
- Work (including but not limited to damages for loss of goodwill,

- * - Branches to main in the C library (which eventually
