AnnaBridge 146:22da6e220af6 200 * This set of functions provides basic matrix math operations.
AnnaBridge 146:22da6e220af6 201 * The functions operate on matrix data structures. For example,
AnnaBridge 146:22da6e220af6 202 * the type
AnnaBridge 146:22da6e220af6 203 * definition for the floating-point matrix structure is shown
AnnaBridge 146:22da6e220af6 204 * below:
AnnaBridge 146:22da6e220af6 205 * <pre>
AnnaBridge 146:22da6e220af6 206 * typedef struct
AnnaBridge 146:22da6e220af6 207 * {
AnnaBridge 146:22da6e220af6 208 * uint16_t numRows; // number of rows of the matrix.
AnnaBridge 146:22da6e220af6 209 * uint16_t numCols; // number of columns of the matrix.
AnnaBridge 146:22da6e220af6 210 * float32_t *pData; // points to the data of the matrix.
AnnaBridge 146:22da6e220af6 211 * } arm_matrix_instance_f32;
AnnaBridge 146:22da6e220af6 212 * </pre>
AnnaBridge 146:22da6e220af6 213 * There are similar definitions for Q15 and Q31 data types.
AnnaBridge 146:22da6e220af6 214 *
AnnaBridge 146:22da6e220af6 215 * The structure specifies the size of the matrix and then points to
AnnaBridge 146:22da6e220af6 216 * an array of data. The array is of size <code>numRows X numCols</code>
AnnaBridge 146:22da6e220af6 217 * and the values are arranged in row order. That is, the
AnnaBridge 146:22da6e220af6 218 * matrix element (i, j) is stored at:
AnnaBridge 146:22da6e220af6 219 * <pre>
AnnaBridge 146:22da6e220af6 220 * pData[i*numCols + j]
AnnaBridge 146:22da6e220af6 221 * </pre>
AnnaBridge 146:22da6e220af6 222 *
AnnaBridge 146:22da6e220af6 223 * \par Init Functions
AnnaBridge 146:22da6e220af6 224 * There is an associated initialization function for each type of matrix
AnnaBridge 146:22da6e220af6 225 * data structure.
AnnaBridge 146:22da6e220af6 226 * The initialization function sets the values of the internal structure fields.
AnnaBridge 146:22da6e220af6 227 * Refer to the function <code>arm_mat_init_f32()</code>, <code>arm_mat_init_q31()</code>
AnnaBridge 146:22da6e220af6 228 * and <code>arm_mat_init_q15()</code> for floating-point, Q31 and Q15 types, respectively.
AnnaBridge 146:22da6e220af6 229 *
AnnaBridge 146:22da6e220af6 230 * \par
AnnaBridge 146:22da6e220af6 231 * Use of the initialization function is optional. However, if initialization function is used
AnnaBridge 146:22da6e220af6 232 * then the instance structure cannot be placed into a const data section.
AnnaBridge 146:22da6e220af6 233 * To place the instance structure in a const data
AnnaBridge 146:22da6e220af6 234 * section, manually initialize the data structure. For example:
AnnaBridge 146:22da6e220af6 235 * <pre>
AnnaBridge 146:22da6e220af6 236 * <code>arm_matrix_instance_f32 S = {nRows, nColumns, pData};</code>
AnnaBridge 146:22da6e220af6 237 * <code>arm_matrix_instance_q31 S = {nRows, nColumns, pData};</code>
AnnaBridge 146:22da6e220af6 238 * <code>arm_matrix_instance_q15 S = {nRows, nColumns, pData};</code>
AnnaBridge 146:22da6e220af6 239 * </pre>

AnnaBridge 146:22da6e220af6 244 * \par Size Checking
AnnaBridge 146:22da6e220af6 245 * By default all of the matrix functions perform size checking on the input and
AnnaBridge 146:22da6e220af6 246 * output matrices. For example, the matrix addition function verifies that the
AnnaBridge 146:22da6e220af6 247 * two input matrices and the output matrix all have the same number of rows and
AnnaBridge 146:22da6e220af6 248 * columns. If the size check fails the functions return:
AnnaBridge 146:22da6e220af6 249 * <pre>
AnnaBridge 146:22da6e220af6 250 * ARM_MATH_SIZE_MISMATCH
AnnaBridge 146:22da6e220af6 251 * </pre>
AnnaBridge 146:22da6e220af6 252 * Otherwise the functions return
AnnaBridge 146:22da6e220af6 253 * <pre>
AnnaBridge 146:22da6e220af6 254 * ARM_MATH_SUCCESS
AnnaBridge 146:22da6e220af6 255 * </pre>
AnnaBridge 146:22da6e220af6 256 * There is some overhead associated with this matrix size checking.
AnnaBridge 146:22da6e220af6 257 * The matrix size checking is enabled via the \#define
AnnaBridge 146:22da6e220af6 258 * <pre>
AnnaBridge 146:22da6e220af6 259 * ARM_MATH_MATRIX_CHECK
AnnaBridge 146:22da6e220af6 260 * </pre>
AnnaBridge 146:22da6e220af6 261 * within the library project settings. By default this macro is defined
AnnaBridge 146:22da6e220af6 262 * and size checking is enabled. By changing the project settings and
AnnaBridge 146:22da6e220af6 263 * undefining this macro size checking is eliminated and the functions
AnnaBridge 146:22da6e220af6 264 * run a bit faster. With size checking disabled the functions always
AnnaBridge 146:22da6e220af6 265 * return <code>ARM_MATH_SUCCESS</code>.

AnnaBridge 146:22da6e220af6 4768 * The PID controller calculates an "error" value as the difference between
AnnaBridge 146:22da6e220af6 4769 * the measured output and the reference input.
AnnaBridge 146:22da6e220af6 4770 * The controller attempts to minimize the error by adjusting the process control inputs.
AnnaBridge 146:22da6e220af6 4771 * The proportional value determines the reaction to the current error,
AnnaBridge 146:22da6e220af6 4772 * the integral value determines the reaction based on the sum of recent errors,
AnnaBridge 146:22da6e220af6 4773 * and the derivative value determines the reaction based on the rate at which the error has been changing.

AnnaBridge 146:22da6e220af6 4776 * The Gains A0, A1, A2 and state variables for a PID controller are stored together in an instance data structure.
AnnaBridge 146:22da6e220af6 4777 * A separate instance structure must be defined for each PID Controller.
AnnaBridge 146:22da6e220af6 4778 * There are separate instance structure declarations for each of the 3 supported data types.
AnnaBridge 146:22da6e220af6 4779 *
AnnaBridge 146:22da6e220af6 4780 * \par Reset Functions
AnnaBridge 146:22da6e220af6 4781 * There is also an associated reset function for each data type which clears the state array.

AnnaBridge 146:22da6e220af6 4783 * \par Initialization Functions
AnnaBridge 146:22da6e220af6 4784 * There is also an associated initialization function for each data type.
AnnaBridge 146:22da6e220af6 4785 * The initialization function performs the following operations:
AnnaBridge 146:22da6e220af6 4786 * - Initializes the Gains A0, A1, A2 from Kp,Ki, Kd gains.
AnnaBridge 146:22da6e220af6 4787 * - Zeros out the values in the state buffer.
AnnaBridge 146:22da6e220af6 4788 *
AnnaBridge 146:22da6e220af6 4789 * \par
AnnaBridge 146:22da6e220af6 4790 * Instance structure cannot be placed into a const data section and it is recommended to use the initialization function.
AnnaBridge 146:22da6e220af6 4791 *
AnnaBridge 146:22da6e220af6 4792 * \par Fixed-Point Behavior
AnnaBridge 146:22da6e220af6 4793 * Care must be taken when using the fixed-point versions of the PID Controller functions.
AnnaBridge 146:22da6e220af6 4794 * In particular, the overflow and saturation behavior of the accumulator used in each function must be considered.

AnnaBridge 146:22da6e220af6 5728 *
AnnaBridge 146:22da6e220af6 5729 * Computes the square root of a number.
AnnaBridge 146:22da6e220af6 5730 * There are separate functions for Q15, Q31, and floating-point data types.
AnnaBridge 146:22da6e220af6 5731 * The square root function is computed using the Newton-Raphson algorithm.
AnnaBridge 146:22da6e220af6 5732 * This is an iterative algorithm of the form:
AnnaBridge 146:22da6e220af6 5733 * <pre>
AnnaBridge 146:22da6e220af6 5734 * x1 = x0 - f(x0)/f'(x0)
AnnaBridge 146:22da6e220af6 5735 * </pre>
AnnaBridge 146:22da6e220af6 5736 * where <code>x1</code> is the current estimate,
AnnaBridge 146:22da6e220af6 5737 * <code>x0</code> is the previous estimate, and
AnnaBridge 146:22da6e220af6 5738 * <code>f'(x0)</code> is the derivative of <code>f()</code> evaluated at <code>x0</code>.
AnnaBridge 146:22da6e220af6 5739 * For the square root function, the algorithm reduces to:
AnnaBridge 146:22da6e220af6 5740 * <pre>
AnnaBridge 146:22da6e220af6 5741 * x0 = in/2 [initial guess]
AnnaBridge 146:22da6e220af6 5742 * x1 = 1/2 * ( x0 + in / x0) [each iteration]
AnnaBridge 146:22da6e220af6 5743 * </pre>

AnnaBridge 146:22da6e220af6 6703 * Bilinear interpolation is an extension of linear interpolation applied to a two dimensional grid.
AnnaBridge 146:22da6e220af6 6704 * The underlying function <code>f(x, y)</code> is sampled on a regular grid and the interpolation process
AnnaBridge 146:22da6e220af6 6705 * determines values between the grid points.
AnnaBridge 146:22da6e220af6 6706 * Bilinear interpolation is equivalent to two step linear interpolation, first in the x-dimension and then in the y-dimension.
AnnaBridge 146:22da6e220af6 6707 * Bilinear interpolation is often used in image processing to rescale images.
AnnaBridge 146:22da6e220af6 6708 * The CMSIS DSP library provides bilinear interpolation functions for Q7, Q15, Q31, and floating-point data types.
