Kojto 115:87f2f5183dfb 63 * 32-bit integer and 32-bit floating-point values.
Kojto 115:87f2f5183dfb 64 *
Kojto 115:87f2f5183dfb 65 * Using the Library
Kojto 115:87f2f5183dfb 66 * ------------
Kojto 115:87f2f5183dfb 67 *
Kojto 115:87f2f5183dfb 68 * The library installer contains prebuilt versions of the libraries in the <code>Lib</code> folder.

Kojto 115:87f2f5183dfb 195 * This set of functions provides basic matrix math operations.
Kojto 115:87f2f5183dfb 196 * The functions operate on matrix data structures. For example,
Kojto 115:87f2f5183dfb 197 * the type
Kojto 115:87f2f5183dfb 198 * definition for the floating-point matrix structure is shown
Kojto 115:87f2f5183dfb 199 * below:
Kojto 115:87f2f5183dfb 200 * <pre>
Kojto 115:87f2f5183dfb 201 * typedef struct
Kojto 115:87f2f5183dfb 202 * {
Kojto 115:87f2f5183dfb 203 * uint16_t numRows; // number of rows of the matrix.

Kojto 115:87f2f5183dfb 207 * </pre>
Kojto 115:87f2f5183dfb 208 * There are similar definitions for Q15 and Q31 data types.
Kojto 115:87f2f5183dfb 209 *
Kojto 115:87f2f5183dfb 210 * The structure specifies the size of the matrix and then points to
Kojto 115:87f2f5183dfb 211 * an array of data. The array is of size <code>numRows X numCols</code>
Kojto 115:87f2f5183dfb 212 * and the values are arranged in row order. That is, the

Kojto 115:87f2f5183dfb 217 *
Kojto 115:87f2f5183dfb 218 * \par Init Functions
Kojto 115:87f2f5183dfb 219 * There is an associated initialization function for each type of matrix
Kojto 115:87f2f5183dfb 220 * data structure.
Kojto 115:87f2f5183dfb 221 * The initialization function sets the values of the internal structure fields.
Kojto 115:87f2f5183dfb 222 * Refer to the function <code>arm_mat_init_f32()</code>, <code>arm_mat_init_q31()</code>
Kojto 115:87f2f5183dfb 223 * and <code>arm_mat_init_q15()</code> for floating-point, Q31 and Q15 types, respectively.
Kojto 115:87f2f5183dfb 224 *
Kojto 115:87f2f5183dfb 225 * \par
Kojto 115:87f2f5183dfb 226 * Use of the initialization function is optional. However, if initialization function is used
Kojto 115:87f2f5183dfb 227 * then the instance structure cannot be placed into a const data section.
Kojto 115:87f2f5183dfb 228 * To place the instance structure in a const data
Kojto 115:87f2f5183dfb 229 * section, manually initialize the data structure. For example:
Kojto 115:87f2f5183dfb 230 * <pre>
Kojto 115:87f2f5183dfb 231 * <code>arm_matrix_instance_f32 S = {nRows, nColumns, pData};</code>
Kojto 115:87f2f5183dfb 232 * <code>arm_matrix_instance_q31 S = {nRows, nColumns, pData};</code>
Kojto 115:87f2f5183dfb 233 * <code>arm_matrix_instance_q15 S = {nRows, nColumns, pData};</code>
Kojto 115:87f2f5183dfb 234 * </pre>
Kojto 115:87f2f5183dfb 235 * where <code>nRows</code> specifies the number of rows, <code>nColumns</code>
Kojto 115:87f2f5183dfb 236 * specifies the number of columns, and <code>pData</code> points to the
Kojto 115:87f2f5183dfb 237 * data array.
Kojto 115:87f2f5183dfb 238 *
Kojto 115:87f2f5183dfb 239 * \par Size Checking
Kojto 115:87f2f5183dfb 240 * By default all of the matrix functions perform size checking on the input and
Kojto 115:87f2f5183dfb 241 * output matrices. For example, the matrix addition function verifies that the
Kojto 115:87f2f5183dfb 242 * two input matrices and the output matrix all have the same number of rows and
Kojto 115:87f2f5183dfb 243 * columns. If the size check fails the functions return:
Kojto 115:87f2f5183dfb 244 * <pre>
Kojto 115:87f2f5183dfb 245 * ARM_MATH_SIZE_MISMATCH
Kojto 115:87f2f5183dfb 246 * </pre>
Kojto 115:87f2f5183dfb 247 * Otherwise the functions return
Kojto 115:87f2f5183dfb 248 * <pre>
Kojto 115:87f2f5183dfb 249 * ARM_MATH_SUCCESS
Kojto 115:87f2f5183dfb 250 * </pre>
Kojto 115:87f2f5183dfb 251 * There is some overhead associated with this matrix size checking.
Kojto 115:87f2f5183dfb 252 * The matrix size checking is enabled via the \#define
Kojto 115:87f2f5183dfb 253 * <pre>
Kojto 115:87f2f5183dfb 254 * ARM_MATH_MATRIX_CHECK
Kojto 115:87f2f5183dfb 255 * </pre>
Kojto 115:87f2f5183dfb 256 * within the library project settings. By default this macro is defined
Kojto 115:87f2f5183dfb 257 * and size checking is enabled. By changing the project settings and
Kojto 115:87f2f5183dfb 258 * undefining this macro size checking is eliminated and the functions
Kojto 115:87f2f5183dfb 259 * run a bit faster. With size checking disabled the functions always
Kojto 115:87f2f5183dfb 260 * return <code>ARM_MATH_SUCCESS</code>.

Kojto 115:87f2f5183dfb 5032 * A Proportional Integral Derivative (PID) controller is a generic feedback control
Kojto 115:87f2f5183dfb 5033 * loop mechanism widely used in industrial control systems.
Kojto 115:87f2f5183dfb 5034 * A PID controller is the most commonly used type of feedback controller.
Kojto 115:87f2f5183dfb 5035 *
Kojto 115:87f2f5183dfb 5036 * This set of functions implements (PID) controllers
Kojto 115:87f2f5183dfb 5037 * for Q15, Q31, and floating-point data types. The functions operate on a single sample
Kojto 115:87f2f5183dfb 5038 * of data and each call to the function returns a single processed value.
Kojto 115:87f2f5183dfb 5039 * <code>S</code> points to an instance of the PID control data structure. <code>in</code>
Kojto 115:87f2f5183dfb 5040 * is the input sample value. The functions return the output value.
Kojto 115:87f2f5183dfb 5041 *
Kojto 115:87f2f5183dfb 5042 * \par Algorithm:
Kojto 115:87f2f5183dfb 5043 * <pre>
Kojto 115:87f2f5183dfb 5044 * y[n] = y[n-1] + A0 * x[n] + A1 * x[n-1] + A2 * x[n-2]

Kojto 115:87f2f5183dfb 5055 * \par
Kojto 115:87f2f5183dfb 5056 * The PID controller calculates an "error" value as the difference between
Kojto 115:87f2f5183dfb 5057 * the measured output and the reference input.
Kojto 115:87f2f5183dfb 5058 * The controller attempts to minimize the error by adjusting the process control inputs.
Kojto 115:87f2f5183dfb 5059 * The proportional value determines the reaction to the current error,
Kojto 115:87f2f5183dfb 5060 * the integral value determines the reaction based on the sum of recent errors,
Kojto 115:87f2f5183dfb 5061 * and the derivative value determines the reaction based on the rate at which the error has been changing.
Kojto 115:87f2f5183dfb 5062 *
Kojto 115:87f2f5183dfb 5063 * \par Instance Structure
Kojto 115:87f2f5183dfb 5064 * The Gains A0, A1, A2 and state variables for a PID controller are stored together in an instance data structure.
Kojto 115:87f2f5183dfb 5065 * A separate instance structure must be defined for each PID Controller.
Kojto 115:87f2f5183dfb 5066 * There are separate instance structure declarations for each of the 3 supported data types.
Kojto 115:87f2f5183dfb 5067 *
Kojto 115:87f2f5183dfb 5068 * \par Reset Functions
Kojto 115:87f2f5183dfb 5069 * There is also an associated reset function for each data type which clears the state array.
Kojto 115:87f2f5183dfb 5070 *
Kojto 115:87f2f5183dfb 5071 * \par Initialization Functions
Kojto 115:87f2f5183dfb 5072 * There is also an associated initialization function for each data type.
Kojto 115:87f2f5183dfb 5073 * The initialization function performs the following operations:
Kojto 115:87f2f5183dfb 5074 * - Initializes the Gains A0, A1, A2 from Kp,Ki, Kd gains.
Kojto 115:87f2f5183dfb 5075 * - Zeros out the values in the state buffer.
Kojto 115:87f2f5183dfb 5076 *
Kojto 115:87f2f5183dfb 5077 * \par
Kojto 115:87f2f5183dfb 5078 * Instance structure cannot be placed into a const data section and it is recommended to use the initialization function.
Kojto 115:87f2f5183dfb 5079 *
Kojto 115:87f2f5183dfb 5080 * \par Fixed-Point Behavior
Kojto 115:87f2f5183dfb 5081 * Care must be taken when using the fixed-point versions of the PID Controller functions.
Kojto 115:87f2f5183dfb 5082 * In particular, the overflow and saturation behavior of the accumulator used in each function must be considered.
Kojto 115:87f2f5183dfb 5083 * Refer to the function specific documentation below for usage guidelines.

Kojto 115:87f2f5183dfb 7084 * Bilinear interpolation is an extension of linear interpolation applied to a two dimensional grid.
Kojto 115:87f2f5183dfb 7085 * The underlying function <code>f(x, y)</code> is sampled on a regular grid and the interpolation process
Kojto 115:87f2f5183dfb 7086 * determines values between the grid points.
Kojto 115:87f2f5183dfb 7087 * Bilinear interpolation is equivalent to two step linear interpolation, first in the x-dimension and then in the y-dimension.
Kojto 115:87f2f5183dfb 7088 * Bilinear interpolation is often used in image processing to rescale images.
Kojto 115:87f2f5183dfb 7089 * The CMSIS DSP library provides bilinear interpolation functions for Q7, Q15, Q31, and floating-point data types.
