phungductung	0:aa3fc5ad02f7	43	*
phungductung	0:aa3fc5ad02f7	44	* Introduction
phungductung	0:aa3fc5ad02f7	45	* ------------
phungductung	0:aa3fc5ad02f7	46	*
phungductung	0:aa3fc5ad02f7	47	* This user manual describes the CMSIS DSP software library,
phungductung	0:aa3fc5ad02f7	48	* a suite of common signal processing functions for use on Cortex-M processor based devices.
phungductung	0:aa3fc5ad02f7	49	*
phungductung	0:aa3fc5ad02f7	50	* The library is divided into a number of functions each covering a specific category:
phungductung	0:aa3fc5ad02f7	51	* - Basic math functions
phungductung	0:aa3fc5ad02f7	52	* - Fast math functions
phungductung	0:aa3fc5ad02f7	53	* - Complex math functions
phungductung	0:aa3fc5ad02f7	54	* - Filters

phungductung	0:aa3fc5ad02f7	63	* 32-bit integer and 32-bit floating-point values.
phungductung	0:aa3fc5ad02f7	64	*
phungductung	0:aa3fc5ad02f7	65	* Using the Library
phungductung	0:aa3fc5ad02f7	66	* ------------
phungductung	0:aa3fc5ad02f7	67	*
phungductung	0:aa3fc5ad02f7	68	* The library installer contains prebuilt versions of the libraries in the <code>Lib</code> folder.

phungductung	0:aa3fc5ad02f7	83	*
phungductung	0:aa3fc5ad02f7	84	* The library functions are declared in the public file <code>arm_math.h</code> which is placed in the <code>Include</code> folder.
phungductung	0:aa3fc5ad02f7	85	* Simply include this file and link the appropriate library in the application and begin calling the library functions. The Library supports single
phungductung	0:aa3fc5ad02f7	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.

phungductung	0:aa3fc5ad02f7	195	* This set of functions provides basic matrix math operations.
phungductung	0:aa3fc5ad02f7	196	* The functions operate on matrix data structures. For example,
phungductung	0:aa3fc5ad02f7	197	* the type
phungductung	0:aa3fc5ad02f7	198	* definition for the floating-point matrix structure is shown
phungductung	0:aa3fc5ad02f7	199	* below:
phungductung	0:aa3fc5ad02f7	200	* <pre>
phungductung	0:aa3fc5ad02f7	201	* typedef struct
phungductung	0:aa3fc5ad02f7	202	* {
phungductung	0:aa3fc5ad02f7	203	* uint16_t numRows; // number of rows of the matrix.
phungductung	0:aa3fc5ad02f7	204	* uint16_t numCols; // number of columns of the matrix.
phungductung	0:aa3fc5ad02f7	205	* float32_t *pData; // points to the data of the matrix.
phungductung	0:aa3fc5ad02f7	206	* } arm_matrix_instance_f32;
phungductung	0:aa3fc5ad02f7	207	* </pre>
phungductung	0:aa3fc5ad02f7	208	* There are similar definitions for Q15 and Q31 data types.
phungductung	0:aa3fc5ad02f7	209	*
phungductung	0:aa3fc5ad02f7	210	* The structure specifies the size of the matrix and then points to
phungductung	0:aa3fc5ad02f7	211	* an array of data. The array is of size <code>numRows X numCols</code>
phungductung	0:aa3fc5ad02f7	212	* and the values are arranged in row order. That is, the
phungductung	0:aa3fc5ad02f7	213	* matrix element (i, j) is stored at:
phungductung	0:aa3fc5ad02f7	214	* <pre>
phungductung	0:aa3fc5ad02f7	215	* pData[i*numCols + j]
phungductung	0:aa3fc5ad02f7	216	* </pre>
phungductung	0:aa3fc5ad02f7	217	*
phungductung	0:aa3fc5ad02f7	218	* \par Init Functions
phungductung	0:aa3fc5ad02f7	219	* There is an associated initialization function for each type of matrix
phungductung	0:aa3fc5ad02f7	220	* data structure.
phungductung	0:aa3fc5ad02f7	221	* The initialization function sets the values of the internal structure fields.
phungductung	0:aa3fc5ad02f7	222	* Refer to the function <code>arm_mat_init_f32()</code>, <code>arm_mat_init_q31()</code>
phungductung	0:aa3fc5ad02f7	223	* and <code>arm_mat_init_q15()</code> for floating-point, Q31 and Q15 types, respectively.
phungductung	0:aa3fc5ad02f7	224	*
phungductung	0:aa3fc5ad02f7	225	* \par
phungductung	0:aa3fc5ad02f7	226	* Use of the initialization function is optional. However, if initialization function is used
phungductung	0:aa3fc5ad02f7	227	* then the instance structure cannot be placed into a const data section.
phungductung	0:aa3fc5ad02f7	228	* To place the instance structure in a const data
phungductung	0:aa3fc5ad02f7	229	* section, manually initialize the data structure. For example:
phungductung	0:aa3fc5ad02f7	230	* <pre>
phungductung	0:aa3fc5ad02f7	231	* <code>arm_matrix_instance_f32 S = {nRows, nColumns, pData};</code>
phungductung	0:aa3fc5ad02f7	232	* <code>arm_matrix_instance_q31 S = {nRows, nColumns, pData};</code>
phungductung	0:aa3fc5ad02f7	233	* <code>arm_matrix_instance_q15 S = {nRows, nColumns, pData};</code>
phungductung	0:aa3fc5ad02f7	234	* </pre>
phungductung	0:aa3fc5ad02f7	235	* where <code>nRows</code> specifies the number of rows, <code>nColumns</code>
phungductung	0:aa3fc5ad02f7	236	* specifies the number of columns, and <code>pData</code> points to the
phungductung	0:aa3fc5ad02f7	237	* data array.
phungductung	0:aa3fc5ad02f7	238	*
phungductung	0:aa3fc5ad02f7	239	* \par Size Checking
phungductung	0:aa3fc5ad02f7	240	* By default all of the matrix functions perform size checking on the input and
phungductung	0:aa3fc5ad02f7	241	* output matrices. For example, the matrix addition function verifies that the
phungductung	0:aa3fc5ad02f7	242	* two input matrices and the output matrix all have the same number of rows and
phungductung	0:aa3fc5ad02f7	243	* columns. If the size check fails the functions return:
phungductung	0:aa3fc5ad02f7	244	* <pre>
