mbed_official 25:ac5b0a371348 231 * Use of the initialization function is optional. However, if initialization function is used
mbed_official 25:ac5b0a371348 232 * then the instance structure cannot be placed into a const data section.
mbed_official 25:ac5b0a371348 233 * To place the instance structure in a const data
mbed_official 25:ac5b0a371348 234 * section, manually initialize the data structure. For example:
mbed_official 25:ac5b0a371348 235 * <pre>
mbed_official 25:ac5b0a371348 236 * <code>arm_matrix_instance_f32 S = {nRows, nColumns, pData};</code>
mbed_official 25:ac5b0a371348 237 * <code>arm_matrix_instance_q31 S = {nRows, nColumns, pData};</code>
mbed_official 25:ac5b0a371348 238 * <code>arm_matrix_instance_q15 S = {nRows, nColumns, pData};</code>
mbed_official 25:ac5b0a371348 239 * </pre>
mbed_official 25:ac5b0a371348 240 * where <code>nRows</code> specifies the number of rows, <code>nColumns</code>
mbed_official 25:ac5b0a371348 241 * specifies the number of columns, and <code>pData</code> points to the
mbed_official 25:ac5b0a371348 242 * data array.
mbed_official 25:ac5b0a371348 243 *
mbed_official 25:ac5b0a371348 244 * \par Size Checking
mbed_official 25:ac5b0a371348 245 * By default all of the matrix functions perform size checking on the input and
mbed_official 25:ac5b0a371348 246 * output matrices. For example, the matrix addition function verifies that the
mbed_official 25:ac5b0a371348 247 * two input matrices and the output matrix all have the same number of rows and
mbed_official 25:ac5b0a371348 248 * columns. If the size check fails the functions return:
mbed_official 25:ac5b0a371348 249 * <pre>
mbed_official 25:ac5b0a371348 250 * ARM_MATH_SIZE_MISMATCH
mbed_official 25:ac5b0a371348 251 * </pre>
mbed_official 25:ac5b0a371348 252 * Otherwise the functions return
mbed_official 25:ac5b0a371348 253 * <pre>
mbed_official 25:ac5b0a371348 254 * ARM_MATH_SUCCESS
mbed_official 25:ac5b0a371348 255 * </pre>
mbed_official 25:ac5b0a371348 256 * There is some overhead associated with this matrix size checking.
mbed_official 25:ac5b0a371348 257 * The matrix size checking is enabled via the \#define
mbed_official 25:ac5b0a371348 258 * <pre>
mbed_official 25:ac5b0a371348 259 * ARM_MATH_MATRIX_CHECK
mbed_official 25:ac5b0a371348 260 * </pre>
mbed_official 25:ac5b0a371348 261 * within the library project settings. By default this macro is defined
mbed_official 25:ac5b0a371348 262 * and size checking is enabled. By changing the project settings and
mbed_official 25:ac5b0a371348 263 * undefining this macro size checking is eliminated and the functions
mbed_official 25:ac5b0a371348 264 * run a bit faster. With size checking disabled the functions always
mbed_official 25:ac5b0a371348 265 * return <code>ARM_MATH_SUCCESS</code>.

mbed_official 25:ac5b0a371348 4839 * the integral value determines the reaction based on the sum of recent errors,

mbed_official 25:ac5b0a371348 4843 * The Gains A0, A1, A2 and state variables for a PID controller are stored together in an instance data structure.
mbed_official 25:ac5b0a371348 4844 * A separate instance structure must be defined for each PID Controller.

mbed_official 25:ac5b0a371348 4852 * The initialization function performs the following operations:

mbed_official 25:ac5b0a371348 4854 * - Zeros out the values in the state buffer.

mbed_official 25:ac5b0a371348 4950 * The function is implemented using a 64-bit internal accumulator.
mbed_official 25:ac5b0a371348 4951 * Both Gains and state variables are represented in 1.15 format and multiplications yield a 2.30 result.
mbed_official 25:ac5b0a371348 4952 * The 2.30 intermediate results are accumulated in a 64-bit accumulator in 34.30 format.
mbed_official 25:ac5b0a371348 4953 * There is no risk of internal overflow with this approach and the full precision of intermediate multiplications is preserved.
mbed_official 25:ac5b0a371348 4954 * After all additions have been performed, the accumulator is truncated to 34.15 format by discarding low 15 bits.
mbed_official 25:ac5b0a371348 4955 * Lastly, the accumulator is saturated to yield a result in 1.15 format.

mbed_official 25:ac5b0a371348 6770 * Bilinear interpolation is an extension of linear interpolation applied to a two dimensional grid.
mbed_official 25:ac5b0a371348 6771 * The underlying function <code>f(x, y)</code> is sampled on a regular grid and the interpolation process
mbed_official 25:ac5b0a371348 6772 * determines values between the grid points.
mbed_official 25:ac5b0a371348 6773 * Bilinear interpolation is equivalent to two step linear interpolation, first in the x-dimension and then in the y-dimension.
mbed_official 25:ac5b0a371348 6774 * Bilinear interpolation is often used in image processing to rescale images.
mbed_official 25:ac5b0a371348 6775 * The CMSIS DSP library provides bilinear interpolation functions for Q7, Q15, Q31, and floating-point data types.
