Kojto 122:f9eeca106725 44 * Introduction
Kojto 122:f9eeca106725 45 * ------------
Kojto 122:f9eeca106725 46 *
Kojto 122:f9eeca106725 47 * This user manual describes the CMSIS DSP software library,
Kojto 122:f9eeca106725 48 * a suite of common signal processing functions for use on Cortex-M processor based devices.

Kojto 122:f9eeca106725 195 * This set of functions provides basic matrix math operations.
Kojto 122:f9eeca106725 196 * The functions operate on matrix data structures. For example,
Kojto 122:f9eeca106725 197 * the type
Kojto 122:f9eeca106725 198 * definition for the floating-point matrix structure is shown
Kojto 122:f9eeca106725 199 * below:
Kojto 122:f9eeca106725 200 * <pre>
Kojto 122:f9eeca106725 201 * typedef struct
Kojto 122:f9eeca106725 202 * {
Kojto 122:f9eeca106725 203 * uint16_t numRows; // number of rows of the matrix.
Kojto 122:f9eeca106725 204 * uint16_t numCols; // number of columns of the matrix.
Kojto 122:f9eeca106725 205 * float32_t *pData; // points to the data of the matrix.
Kojto 122:f9eeca106725 206 * } arm_matrix_instance_f32;
Kojto 122:f9eeca106725 207 * </pre>
Kojto 122:f9eeca106725 208 * There are similar definitions for Q15 and Q31 data types.
Kojto 122:f9eeca106725 209 *
Kojto 122:f9eeca106725 210 * The structure specifies the size of the matrix and then points to
Kojto 122:f9eeca106725 211 * an array of data. The array is of size <code>numRows X numCols</code>
Kojto 122:f9eeca106725 212 * and the values are arranged in row order. That is, the
Kojto 122:f9eeca106725 213 * matrix element (i, j) is stored at:
Kojto 122:f9eeca106725 214 * <pre>
Kojto 122:f9eeca106725 215 * pData[i*numCols + j]
Kojto 122:f9eeca106725 216 * </pre>
Kojto 122:f9eeca106725 217 *
Kojto 122:f9eeca106725 218 * \par Init Functions
Kojto 122:f9eeca106725 219 * There is an associated initialization function for each type of matrix
Kojto 122:f9eeca106725 220 * data structure.
Kojto 122:f9eeca106725 221 * The initialization function sets the values of the internal structure fields.
Kojto 122:f9eeca106725 222 * Refer to the function <code>arm_mat_init_f32()</code>, <code>arm_mat_init_q31()</code>
Kojto 122:f9eeca106725 223 * and <code>arm_mat_init_q15()</code> for floating-point, Q31 and Q15 types, respectively.
Kojto 122:f9eeca106725 224 *
Kojto 122:f9eeca106725 225 * \par
Kojto 122:f9eeca106725 226 * Use of the initialization function is optional. However, if initialization function is used
Kojto 122:f9eeca106725 227 * then the instance structure cannot be placed into a const data section.
Kojto 122:f9eeca106725 228 * To place the instance structure in a const data
Kojto 122:f9eeca106725 229 * section, manually initialize the data structure. For example:
Kojto 122:f9eeca106725 230 * <pre>
Kojto 122:f9eeca106725 231 * <code>arm_matrix_instance_f32 S = {nRows, nColumns, pData};</code>
Kojto 122:f9eeca106725 232 * <code>arm_matrix_instance_q31 S = {nRows, nColumns, pData};</code>
Kojto 122:f9eeca106725 233 * <code>arm_matrix_instance_q15 S = {nRows, nColumns, pData};</code>
Kojto 122:f9eeca106725 234 * </pre>
Kojto 122:f9eeca106725 235 * where <code>nRows</code> specifies the number of rows, <code>nColumns</code>
Kojto 122:f9eeca106725 236 * specifies the number of columns, and <code>pData</code> points to the
Kojto 122:f9eeca106725 237 * data array.
Kojto 122:f9eeca106725 238 *
Kojto 122:f9eeca106725 239 * \par Size Checking
Kojto 122:f9eeca106725 240 * By default all of the matrix functions perform size checking on the input and
Kojto 122:f9eeca106725 241 * output matrices. For example, the matrix addition function verifies that the
Kojto 122:f9eeca106725 242 * two input matrices and the output matrix all have the same number of rows and
Kojto 122:f9eeca106725 243 * columns. If the size check fails the functions return:
Kojto 122:f9eeca106725 244 * <pre>
Kojto 122:f9eeca106725 245 * ARM_MATH_SIZE_MISMATCH
Kojto 122:f9eeca106725 246 * </pre>
Kojto 122:f9eeca106725 247 * Otherwise the functions return
Kojto 122:f9eeca106725 248 * <pre>
Kojto 122:f9eeca106725 249 * ARM_MATH_SUCCESS
Kojto 122:f9eeca106725 250 * </pre>
Kojto 122:f9eeca106725 251 * There is some overhead associated with this matrix size checking.
Kojto 122:f9eeca106725 252 * The matrix size checking is enabled via the \#define
Kojto 122:f9eeca106725 253 * <pre>
Kojto 122:f9eeca106725 254 * ARM_MATH_MATRIX_CHECK
Kojto 122:f9eeca106725 255 * </pre>
Kojto 122:f9eeca106725 256 * within the library project settings. By default this macro is defined
Kojto 122:f9eeca106725 257 * and size checking is enabled. By changing the project settings and
Kojto 122:f9eeca106725 258 * undefining this macro size checking is eliminated and the functions
Kojto 122:f9eeca106725 259 * run a bit faster. With size checking disabled the functions always
Kojto 122:f9eeca106725 260 * return <code>ARM_MATH_SUCCESS</code>.

Kojto 122:f9eeca106725 5058 * The controller attempts to minimize the error by adjusting the process control inputs.
Kojto 122:f9eeca106725 5059 * The proportional value determines the reaction to the current error,
Kojto 122:f9eeca106725 5060 * the integral value determines the reaction based on the sum of recent errors,
Kojto 122:f9eeca106725 5061 * and the derivative value determines the reaction based on the rate at which the error has been changing.

Kojto 122:f9eeca106725 5064 * The Gains A0, A1, A2 and state variables for a PID controller are stored together in an instance data structure.
Kojto 122:f9eeca106725 5065 * A separate instance structure must be defined for each PID Controller.
Kojto 122:f9eeca106725 5066 * There are separate instance structure declarations for each of the 3 supported data types.

Kojto 122:f9eeca106725 5068 * \par Reset Functions
Kojto 122:f9eeca106725 5069 * There is also an associated reset function for each data type which clears the state array.

Kojto 122:f9eeca106725 5071 * \par Initialization Functions
Kojto 122:f9eeca106725 5072 * There is also an associated initialization function for each data type.
Kojto 122:f9eeca106725 5073 * The initialization function performs the following operations:
Kojto 122:f9eeca106725 5074 * - Initializes the Gains A0, A1, A2 from Kp,Ki, Kd gains.
Kojto 122:f9eeca106725 5075 * - Zeros out the values in the state buffer.
Kojto 122:f9eeca106725 5076 *
Kojto 122:f9eeca106725 5077 * \par
Kojto 122:f9eeca106725 5078 * Instance structure cannot be placed into a const data section and it is recommended to use the initialization function.

Kojto 122:f9eeca106725 5080 * \par Fixed-Point Behavior
Kojto 122:f9eeca106725 5081 * Care must be taken when using the fixed-point versions of the PID Controller functions.
Kojto 122:f9eeca106725 5082 * In particular, the overflow and saturation behavior of the accumulator used in each function must be considered.

Kojto 122:f9eeca106725 7086 * determines values between the grid points.
Kojto 122:f9eeca106725 7087 * Bilinear interpolation is equivalent to two step linear interpolation, first in the x-dimension and then in the y-dimension.
Kojto 122:f9eeca106725 7088 * Bilinear interpolation is often used in image processing to rescale images.
