MikamiUitOpen	2:dcaee06f6ccb	44	* Introduction
MikamiUitOpen	2:dcaee06f6ccb	45	* ------------
MikamiUitOpen	2:dcaee06f6ccb	46	*
MikamiUitOpen	2:dcaee06f6ccb	47	* This user manual describes the CMSIS DSP software library,
MikamiUitOpen	2:dcaee06f6ccb	48	* a suite of common signal processing functions for use on Cortex-M processor based devices.
MikamiUitOpen	2:dcaee06f6ccb	49	*
MikamiUitOpen	2:dcaee06f6ccb	50	* The library is divided into a number of functions each covering a specific category:
MikamiUitOpen	2:dcaee06f6ccb	51	* - Basic math functions
MikamiUitOpen	2:dcaee06f6ccb	52	* - Fast math functions
MikamiUitOpen	2:dcaee06f6ccb	53	* - Complex math functions
MikamiUitOpen	2:dcaee06f6ccb	54	* - Filters
MikamiUitOpen	2:dcaee06f6ccb	55	* - Matrix functions
MikamiUitOpen	2:dcaee06f6ccb	56	* - Transforms

MikamiUitOpen	2:dcaee06f6ccb	59	* - Support functions
MikamiUitOpen	2:dcaee06f6ccb	60	* - Interpolation functions
MikamiUitOpen	2:dcaee06f6ccb	61	*
MikamiUitOpen	2:dcaee06f6ccb	62	* The library has separate functions for operating on 8-bit integers, 16-bit integers,
MikamiUitOpen	2:dcaee06f6ccb	63	* 32-bit integer and 32-bit floating-point values.
MikamiUitOpen	2:dcaee06f6ccb	64	*
MikamiUitOpen	2:dcaee06f6ccb	65	* Using the Library
MikamiUitOpen	2:dcaee06f6ccb	66	* ------------
MikamiUitOpen	2:dcaee06f6ccb	67	*
MikamiUitOpen	2:dcaee06f6ccb	68	* The library installer contains prebuilt versions of the libraries in the <code>Lib</code> folder.
MikamiUitOpen	2:dcaee06f6ccb	69	* - arm_cortexM7lfdp_math.lib (Little endian and Double Precision Floating Point Unit on Cortex-M7)
MikamiUitOpen	2:dcaee06f6ccb	70	* - arm_cortexM7bfdp_math.lib (Big endian and Double Precision Floating Point Unit on Cortex-M7)

MikamiUitOpen	2:dcaee06f6ccb	77	* - arm_cortexM4l_math.lib (Little endian on Cortex-M4)
MikamiUitOpen	2:dcaee06f6ccb	78	* - arm_cortexM4b_math.lib (Big endian on Cortex-M4)

MikamiUitOpen	2:dcaee06f6ccb	80	* - arm_cortexM3b_math.lib (Big endian on Cortex-M3)
MikamiUitOpen	2:dcaee06f6ccb	81	* - arm_cortexM0l_math.lib (Little endian on Cortex-M0 / CortexM0+)
MikamiUitOpen	2:dcaee06f6ccb	82	* - arm_cortexM0b_math.lib (Big endian on Cortex-M0 / CortexM0+)
MikamiUitOpen	2:dcaee06f6ccb	83	*
MikamiUitOpen	2:dcaee06f6ccb	84	* The library functions are declared in the public file <code>arm_math.h</code> which is placed in the <code>Include</code> folder.
MikamiUitOpen	2:dcaee06f6ccb	85	* Simply include this file and link the appropriate library in the application and begin calling the library functions. The Library supports single
MikamiUitOpen	2:dcaee06f6ccb	86	* public header file <code> arm_math.h</code> for Cortex-M7/M4/M3/M0/M0+ with little endian and big endian. Same header file will be used for floating point unit(FPU) variants.
MikamiUitOpen	2:dcaee06f6ccb	87	* Define the appropriate pre processor MACRO ARM_MATH_CM7 or ARM_MATH_CM4 or ARM_MATH_CM3 or
MikamiUitOpen	2:dcaee06f6ccb	88	* ARM_MATH_CM0 or ARM_MATH_CM0PLUS depending on the target processor in the application.
MikamiUitOpen	2:dcaee06f6ccb	89	*
MikamiUitOpen	2:dcaee06f6ccb	90	* Examples
MikamiUitOpen	2:dcaee06f6ccb	91	* --------
MikamiUitOpen	2:dcaee06f6ccb	92	*

MikamiUitOpen	2:dcaee06f6ccb	195	* This set of functions provides basic matrix math operations.
MikamiUitOpen	2:dcaee06f6ccb	196	* The functions operate on matrix data structures. For example,
MikamiUitOpen	2:dcaee06f6ccb	197	* the type
MikamiUitOpen	2:dcaee06f6ccb	198	* definition for the floating-point matrix structure is shown
MikamiUitOpen	2:dcaee06f6ccb	199	* below:
MikamiUitOpen	2:dcaee06f6ccb	200	* <pre>
MikamiUitOpen	2:dcaee06f6ccb	201	* typedef struct
MikamiUitOpen	2:dcaee06f6ccb	202	* {
MikamiUitOpen	2:dcaee06f6ccb	203	* uint16_t numRows; // number of rows of the matrix.

MikamiUitOpen	2:dcaee06f6ccb	205	* float32_t *pData; // points to the data of the matrix.
MikamiUitOpen	2:dcaee06f6ccb	206	* } arm_matrix_instance_f32;
MikamiUitOpen	2:dcaee06f6ccb	207	* </pre>
MikamiUitOpen	2:dcaee06f6ccb	208	* There are similar definitions for Q15 and Q31 data types.
MikamiUitOpen	2:dcaee06f6ccb	209	*
MikamiUitOpen	2:dcaee06f6ccb	210	* The structure specifies the size of the matrix and then points to
MikamiUitOpen	2:dcaee06f6ccb	211	* an array of data. The array is of size <code>numRows X numCols</code>
MikamiUitOpen	2:dcaee06f6ccb	212	* and the values are arranged in row order. That is, the
MikamiUitOpen	2:dcaee06f6ccb	213	* matrix element (i, j) is stored at:
MikamiUitOpen	2:dcaee06f6ccb	214	* <pre>
MikamiUitOpen	2:dcaee06f6ccb	215	* pData[i*numCols + j]
MikamiUitOpen	2:dcaee06f6ccb	216	* </pre>
MikamiUitOpen	2:dcaee06f6ccb	217	*
MikamiUitOpen	2:dcaee06f6ccb	218	* \par Init Functions
MikamiUitOpen	2:dcaee06f6ccb	219	* There is an associated initialization function for each type of matrix
MikamiUitOpen	2:dcaee06f6ccb	220	* data structure.
MikamiUitOpen	2:dcaee06f6ccb	221	* The initialization function sets the values of the internal structure fields.
MikamiUitOpen	2:dcaee06f6ccb	222	* Refer to the function <code>arm_mat_init_f32()</code>, <code>arm_mat_init_q31()</code>
MikamiUitOpen	2:dcaee06f6ccb	223	* and <code>arm_mat_init_q15()</code> for floating-point, Q31 and Q15 types, respectively.
MikamiUitOpen	2:dcaee06f6ccb	224	*
MikamiUitOpen	2:dcaee06f6ccb	225	* \par
MikamiUitOpen	2:dcaee06f6ccb	226	* Use of the initialization function is optional. However, if initialization function is used
MikamiUitOpen	2:dcaee06f6ccb	227	* then the instance structure cannot be placed into a const data section.
MikamiUitOpen	2:dcaee06f6ccb	228	* To place the instance structure in a const data
MikamiUitOpen	2:dcaee06f6ccb	229	* section, manually initialize the data structure. For example:
MikamiUitOpen	2:dcaee06f6ccb	230	* <pre>
MikamiUitOpen	2:dcaee06f6ccb	231	* <code>arm_matrix_instance_f32 S = {nRows, nColumns, pData};</code>
MikamiUitOpen	2:dcaee06f6ccb	232	* <code>arm_matrix_instance_q31 S = {nRows, nColumns, pData};</code>
MikamiUitOpen	2:dcaee06f6ccb	233	* <code>arm_matrix_instance_q15 S = {nRows, nColumns, pData};</code>
MikamiUitOpen	2:dcaee06f6ccb	234	* </pre>
MikamiUitOpen	2:dcaee06f6ccb	235	* where <code>nRows</code> specifies the number of rows, <code>nColumns</code>
MikamiUitOpen	2:dcaee06f6ccb	236	* specifies the number of columns, and <code>pData</code> points to the
MikamiUitOpen	2:dcaee06f6ccb	237	* data array.
MikamiUitOpen	2:dcaee06f6ccb	238	*
MikamiUitOpen	2:dcaee06f6ccb	239	* \par Size Checking
MikamiUitOpen	2:dcaee06f6ccb	240	* By default all of the matrix functions perform size checking on the input and
MikamiUitOpen	2:dcaee06f6ccb	241	* output matrices. For example, the matrix addition function verifies that the
MikamiUitOpen	2:dcaee06f6ccb	242	* two input matrices and the output matrix all have the same number of rows and
MikamiUitOpen	2:dcaee06f6ccb	243	* columns. If the size check fails the functions return:
MikamiUitOpen	2:dcaee06f6ccb	244	* <pre>
MikamiUitOpen	2:dcaee06f6ccb	245	* ARM_MATH_SIZE_MISMATCH
MikamiUitOpen	2:dcaee06f6ccb	246	* </pre>
MikamiUitOpen	2:dcaee06f6ccb	247	* Otherwise the functions return
MikamiUitOpen	2:dcaee06f6ccb	248	* <pre>

MikamiUitOpen	2:dcaee06f6ccb	5059	* The proportional value determines the reaction to the current error,
MikamiUitOpen	2:dcaee06f6ccb	5060	* the integral value determines the reaction based on the sum of recent errors,
MikamiUitOpen	2:dcaee06f6ccb	5061	* and the derivative value determines the reaction based on the rate at which the error has been changing.

MikamiUitOpen	2:dcaee06f6ccb	5063	* \par Instance Structure
MikamiUitOpen	2:dcaee06f6ccb	5064	* The Gains A0, A1, A2 and state variables for a PID controller are stored together in an instance data structure.
MikamiUitOpen	2:dcaee06f6ccb	5065	* A separate instance structure must be defined for each PID Controller.
MikamiUitOpen	2:dcaee06f6ccb	5066	* There are separate instance structure declarations for each of the 3 supported data types.
MikamiUitOpen	2:dcaee06f6ccb	5067	*
MikamiUitOpen	2:dcaee06f6ccb	5068	* \par Reset Functions
MikamiUitOpen	2:dcaee06f6ccb	5069	* There is also an associated reset function for each data type which clears the state array.

MikamiUitOpen	2:dcaee06f6ccb	5072	* There is also an associated initialization function for each data type.
MikamiUitOpen	2:dcaee06f6ccb	5073	* The initialization function performs the following operations:
MikamiUitOpen	2:dcaee06f6ccb	5074	* - Initializes the Gains A0, A1, A2 from Kp,Ki, Kd gains.
MikamiUitOpen	2:dcaee06f6ccb	5075	* - Zeros out the values in the state buffer.

MikamiUitOpen	2:dcaee06f6ccb	5080	* \par Fixed-Point Behavior
MikamiUitOpen	2:dcaee06f6ccb	5081	* Care must be taken when using the fixed-point versions of the PID Controller functions.
MikamiUitOpen	2:dcaee06f6ccb	5082	* In particular, the overflow and saturation behavior of the accumulator used in each function must be considered.
