emilmont | 1:fdd22bb7aa52 | 218 | * \par Init Functions |
emilmont | 1:fdd22bb7aa52 | 219 | * There is an associated initialization function for each type of matrix |
emilmont | 1:fdd22bb7aa52 | 220 | * data structure. |
emilmont | 1:fdd22bb7aa52 | 221 | * The initialization function sets the values of the internal structure fields. |
emilmont | 1:fdd22bb7aa52 | 222 | * Refer to the function <code>arm_mat_init_f32()</code>, <code>arm_mat_init_q31()</code> |
emilmont | 1:fdd22bb7aa52 | 223 | * and <code>arm_mat_init_q15()</code> for floating-point, Q31 and Q15 types, respectively. |
emilmont | 1:fdd22bb7aa52 | 224 | * |
emilmont | 1:fdd22bb7aa52 | 225 | * \par |
emilmont | 1:fdd22bb7aa52 | 226 | * Use of the initialization function is optional. However, if initialization function is used |
emilmont | 1:fdd22bb7aa52 | 227 | * then the instance structure cannot be placed into a const data section. |
emilmont | 1:fdd22bb7aa52 | 228 | * To place the instance structure in a const data |
emilmont | 1:fdd22bb7aa52 | 229 | * section, manually initialize the data structure. For example: |
emilmont | 1:fdd22bb7aa52 | 230 | * <pre> |
emilmont | 1:fdd22bb7aa52 | 231 | * <code>arm_matrix_instance_f32 S = {nRows, nColumns, pData};</code> |
emilmont | 1:fdd22bb7aa52 | 232 | * <code>arm_matrix_instance_q31 S = {nRows, nColumns, pData};</code> |
emilmont | 1:fdd22bb7aa52 | 233 | * <code>arm_matrix_instance_q15 S = {nRows, nColumns, pData};</code> |
emilmont | 1:fdd22bb7aa52 | 234 | * </pre> |
emilmont | 1:fdd22bb7aa52 | 235 | * where <code>nRows</code> specifies the number of rows, <code>nColumns</code> |
emilmont | 1:fdd22bb7aa52 | 236 | * specifies the number of columns, and <code>pData</code> points to the |
emilmont | 1:fdd22bb7aa52 | 237 | * data array. |
emilmont | 1:fdd22bb7aa52 | 238 | * |
emilmont | 1:fdd22bb7aa52 | 239 | * \par Size Checking |
emilmont | 1:fdd22bb7aa52 | 240 | * By default all of the matrix functions perform size checking on the input and |
emilmont | 1:fdd22bb7aa52 | 241 | * output matrices. For example, the matrix addition function verifies that the |
emilmont | 1:fdd22bb7aa52 | 242 | * two input matrices and the output matrix all have the same number of rows and |
emilmont | 1:fdd22bb7aa52 | 243 | * columns. If the size check fails the functions return: |
emilmont | 1:fdd22bb7aa52 | 244 | * <pre> |
emilmont | 1:fdd22bb7aa52 | 245 | * ARM_MATH_SIZE_MISMATCH |
emilmont | 1:fdd22bb7aa52 | 246 | * </pre> |
emilmont | 1:fdd22bb7aa52 | 247 | * Otherwise the functions return |
emilmont | 1:fdd22bb7aa52 | 248 | * <pre> |
emilmont | 1:fdd22bb7aa52 | 249 | * ARM_MATH_SUCCESS |
emilmont | 1:fdd22bb7aa52 | 250 | * </pre> |
emilmont | 1:fdd22bb7aa52 | 251 | * There is some overhead associated with this matrix size checking. |
emilmont | 1:fdd22bb7aa52 | 252 | * The matrix size checking is enabled via the \#define |
emilmont | 1:fdd22bb7aa52 | 253 | * <pre> |
emilmont | 1:fdd22bb7aa52 | 254 | * ARM_MATH_MATRIX_CHECK |
emilmont | 1:fdd22bb7aa52 | 255 | * </pre> |
emilmont | 1:fdd22bb7aa52 | 256 | * within the library project settings. By default this macro is defined |
emilmont | 1:fdd22bb7aa52 | 257 | * and size checking is enabled. By changing the project settings and |
emilmont | 1:fdd22bb7aa52 | 258 | * undefining this macro size checking is eliminated and the functions |
emilmont | 1:fdd22bb7aa52 | 259 | * run a bit faster. With size checking disabled the functions always |
emilmont | 1:fdd22bb7aa52 | 260 | * return <code>ARM_MATH_SUCCESS</code>. |

emilmont | 1:fdd22bb7aa52 | 4755 | * The PID controller calculates an "error" value as the difference between |
emilmont | 1:fdd22bb7aa52 | 4756 | * the measured output and the reference input. |
mbed_official | 3:7a284390b0ce | 4757 | * The controller attempts to minimize the error by adjusting the process control inputs. |
mbed_official | 3:7a284390b0ce | 4758 | * The proportional value determines the reaction to the current error, |
mbed_official | 3:7a284390b0ce | 4759 | * the integral value determines the reaction based on the sum of recent errors, |
emilmont | 1:fdd22bb7aa52 | 4760 | * and the derivative value determines the reaction based on the rate at which the error has been changing. |

mbed_official | 3:7a284390b0ce | 4763 | * The Gains A0, A1, A2 and state variables for a PID controller are stored together in an instance data structure. |
mbed_official | 3:7a284390b0ce | 4764 | * A separate instance structure must be defined for each PID Controller. |
mbed_official | 3:7a284390b0ce | 4765 | * There are separate instance structure declarations for each of the 3 supported data types. |
mbed_official | 3:7a284390b0ce | 4766 | * |
mbed_official | 3:7a284390b0ce | 4767 | * \par Reset Functions |
mbed_official | 3:7a284390b0ce | 4768 | * There is also an associated reset function for each data type which clears the state array. |
emilmont | 1:fdd22bb7aa52 | 4769 | * |
mbed_official | 3:7a284390b0ce | 4770 | * \par Initialization Functions |
mbed_official | 3:7a284390b0ce | 4771 | * There is also an associated initialization function for each data type. |
mbed_official | 3:7a284390b0ce | 4772 | * The initialization function performs the following operations: |
emilmont | 1:fdd22bb7aa52 | 4773 | * - Initializes the Gains A0, A1, A2 from Kp,Ki, Kd gains. |
mbed_official | 3:7a284390b0ce | 4774 | * - Zeros out the values in the state buffer. |
mbed_official | 3:7a284390b0ce | 4775 | * |
mbed_official | 3:7a284390b0ce | 4776 | * \par |
mbed_official | 3:7a284390b0ce | 4777 | * Instance structure cannot be placed into a const data section and it is recommended to use the initialization function. |
emilmont | 1:fdd22bb7aa52 | 4778 | * |
mbed_official | 3:7a284390b0ce | 4779 | * \par Fixed-Point Behavior |
mbed_official | 3:7a284390b0ce | 4780 | * Care must be taken when using the fixed-point versions of the PID Controller functions. |
mbed_official | 3:7a284390b0ce | 4781 | * In particular, the overflow and saturation behavior of the accumulator used in each function must be considered. |
mbed_official | 3:7a284390b0ce | 4782 | * Refer to the function specific documentation below for usage guidelines. |

emilmont | 1:fdd22bb7aa52 | 6690 | * Bilinear interpolation is an extension of linear interpolation applied to a two dimensional grid. |
emilmont | 1:fdd22bb7aa52 | 6691 | * The underlying function <code>f(x, y)</code> is sampled on a regular grid and the interpolation process |
emilmont | 1:fdd22bb7aa52 | 6692 | * determines values between the grid points. |
emilmont | 1:fdd22bb7aa52 | 6693 | * Bilinear interpolation is equivalent to two step linear interpolation, first in the x-dimension and then in the y-dimension. |
emilmont | 1:fdd22bb7aa52 | 6694 | * Bilinear interpolation is often used in image processing to rescale images. |
