+/**
+ \mainpage CMSIS DSP Software Library
+ *
+ * <b>Introduction</b>
+ *
+ * This user manual describes the CMSIS DSP software library,
+ * a suite of common signal processing functions for use on Cortex-M processor based devices.
+ *
+ * The library is divided into a number of modules each covering a specific category:
+ * - Basic math functions
+ * - Fast math functions
+ * - Complex math functions
+ * - Filters
+ * - Matrix functions
+ * - Transforms
+ * - Motor control functions
+ * - Statistical functions
+ * - Support functions
+ * - Interpolation functions
+ *
+ * The library has separate functions for operating on 8-bit integers, 16-bit integers,
+ * 32-bit integer and 32-bit floating-point values.
+ *
+ * <b>Processor Support</b>
+ *
+ * The library is completely written in C and is fully CMSIS compliant.
+ * High performance is achieved through maximum use of Cortex-M4 intrinsics.
+ *
+ * The supplied library source code also builds and runs on the Cortex-M3 and Cortex-M0 processor,
+ * with the DSP intrinsics being emulated through software.
+ *
+ *
+ * <b>Toolchain Support</b>
+ *
+ * The library has been developed and tested with MDK-ARM version 4.21.
+ * The library is being tested in GCC and IAR toolchains and updates on this activity will be made available shortly.
+ *
+ * <b>Using the Library</b>
+ *
+ * The library installer contains prebuilt versions of the libraries in the <code>Lib</code> folder.
+ * - arm_cortexM4lf_math.lib (Little endian and Floating Point Unit on Cortex-M4)
+ * - arm_cortexM4bf_math.lib (Big endian and Floating Point Unit on Cortex-M4)
+ * - arm_cortexM4l_math.lib (Little endian on Cortex-M4)
+ * - arm_cortexM4b_math.lib (Big endian on Cortex-M4)
+ * - arm_cortexM3l_math.lib (Little endian on Cortex-M3)
+ * - arm_cortexM3b_math.lib (Big endian on Cortex-M3)
+ * - arm_cortexM0l_math.lib (Little endian on Cortex-M0)
+ * - arm_cortexM0b_math.lib (Big endian on Cortex-M3)
+ *
+ * The library functions are declared in the public file <code>arm_math.h</code> which is placed in the <code>Include</code> folder.
+ * Simply include this file and link the appropriate library in the application and begin calling the library functions. The Library supports single
+ * public header file <code> arm_math.h</code> for Cortex-M4/M3/M0 with little endian and big endian. Same header file will be used for floating point unit(FPU) variants.
+ * Define the appropriate pre processor MACRO ARM_MATH_CM4 or ARM_MATH_CM3 or
+ * ARM_MATH_CM0 depending on the target processor in the application.
+ *
+ * <b>Examples</b>
+ *
+ * The library ships with a number of examples which demonstrate how to use the library functions.
+ *
+ * <b>Building the Library</b>
+ *
+ * The library installer contains project files to re build libraries on MDK Tool chain in the <code>CMSIS\DSP_Lib\Source\ARM</code> folder.
+ * - arm_cortexM0b_math.uvproj
+ * - arm_cortexM0l_math.uvproj
+ * - arm_cortexM3b_math.uvproj
+ * - arm_cortexM3l_math.uvproj
+ * - arm_cortexM4b_math.uvproj
+ * - arm_cortexM4l_math.uvproj
+ * - arm_cortexM4bf_math.uvproj
+ * - arm_cortexM4lf_math.uvproj
+ *
+ * Each library project have differant pre-processor macros.
+ *
+ * <b>ARM_MATH_CMx:</b>
+ * Define macro ARM_MATH_CM4 for building the library on Cortex-M4 target, ARM_MATH_CM3 for building library on Cortex-M3 target
+ * and ARM_MATH_CM0 for building library on cortex-M0 target.
+ *
+ * <b>ARM_MATH_BIG_ENDIAN:</b>
+ * Define macro ARM_MATH_BIG_ENDIAN to build the library for big endian targets. By default library builds for little endian targets.
+ *
+ * <b>ARM_MATH_MATRIX_CHECK:</b>
+ * Define macro for checking on the input and output sizes of matrices
+ *
+ * <b>ARM_MATH_ROUNDING:</b>
+ * Define macro for rounding on support functions
+ *
+ * <b>__FPU_PRESENT:</b>
+ * Initialize macro __FPU_PRESENT = 1 when building on FPU supported Targets. Enable this macro for M4bf and M4lf libraries
+ *
+ *
+ * The project can be built by opening the appropriate project in MDK-ARM 4.21 chain and defining the optional pre processor MACROs detailed above.
+ *

+ * This set of functions provides a fast approximation to sine, cosine, and square root.
+ * As compared to most of the other functions in the CMSIS math library, the fast math functions
+ * operate on individual values and not arrays.
+ * There are separate functions for Q15, Q31, and floating-point data.

+
+/**
+ * @defgroup groupMatrix Matrix Functions
+ *
+ * This set of functions provides basic matrix math operations.
+ * The functions operate on matrix data structures. For example,
+ * the type
+ * definition for the floating-point matrix structure is shown
+ * below:
+ * <pre>
+ * typedef struct
+ * {
+ * uint16_t numRows; // number of rows of the matrix.
+ * uint16_t numCols; // number of columns of the matrix.
+ * float32_t *pData; // points to the data of the matrix.
+ * } arm_matrix_instance_f32;
+ * </pre>
+ * There are similar definitions for Q15 and Q31 data types.
+ *
+ * The structure specifies the size of the matrix and then points to
+ * an array of data. The array is of size <code>numRows X numCols</code>
+ * and the values are arranged in row order. That is, the
+ * matrix element (i, j) is stored at:
+ * <pre>
+ * pData[i*numCols + j]
+ * </pre>
+ *
+ * \par Init Functions
+ * There is an associated initialization function for each type of matrix
+ * data structure.
+ * The initialization function sets the values of the internal structure fields.
+ * Refer to the function <code>arm_mat_init_f32()</code>, <code>arm_mat_init_q31()</code>
+ * and <code>arm_mat_init_q15()</code> for floating-point, Q31 and Q15 types, respectively.
+ *
+ * \par
+ * Use of the initialization function is optional. However, if initialization function is used
+ * then the instance structure cannot be placed into a const data section.
+ * To place the instance structure in a const data
+ * section, manually initialize the data structure. For example:
+ * <pre>
+ * <code>arm_matrix_instance_f32 S = {nRows, nColumns, pData};</code>
+ * <code>arm_matrix_instance_q31 S = {nRows, nColumns, pData};</code>
+ * <code>arm_matrix_instance_q15 S = {nRows, nColumns, pData};</code>
+ * </pre>
+ * where <code>nRows</code> specifies the number of rows, <code>nColumns</code>
+ * specifies the number of columns, and <code>pData</code> points to the
+ * data array.
+ *
+ * \par Size Checking
+ * By default all of the matrix functions perform size checking on the input and
+ * output matrices. For example, the matrix addition function verifies that the
+ * two input matrices and the output matrix all have the same number of rows and
+ * columns. If the size check fails the functions return:
+ * <pre>
+ * ARM_MATH_SIZE_MISMATCH
+ * </pre>
+ * Otherwise the functions return
+ * <pre>
+ * ARM_MATH_SUCCESS
+ * </pre>
+ * There is some overhead associated with this matrix size checking.
+ * The matrix size checking is enabled via the #define
+ * <pre>
+ * ARM_MATH_MATRIX_CHECK
+ * </pre>
+ * within the library project settings. By default this macro is defined
+ * and size checking is enabled. By changing the project settings and
+ * undefining this macro size checking is eliminated and the functions
+ * run a bit faster. With size checking disabled the functions always
+ * return <code>ARM_MATH_SUCCESS</code>.

+ * \image html PID.gif "Proportional Integral Derivative Controller"
+ *
+ * \par
+ * The PID controller calculates an "error" value as the difference between
+ * the measured output and the reference input.
+ * The controller attempts to minimize the error by adjusting the process control inputs.
+ * The proportional value determines the reaction to the current error,
+ * the integral value determines the reaction based on the sum of recent errors,
+ * and the derivative value determines the reaction based on the rate at which the error has been changing.
+ *
+ * \par Instance Structure
+ * The Gains A0, A1, A2 and state variables for a PID controller are stored together in an instance data structure.
+ * A separate instance structure must be defined for each PID Controller.
+ * There are separate instance structure declarations for each of the 3 supported data types.
+ *
+ * \par Reset Functions
+ * There is also an associated reset function for each data type which clears the state array.
+ *
+ * \par Initialization Functions
+ * There is also an associated initialization function for each data type.
+ * The initialization function performs the following operations:
+ * - Initializes the Gains A0, A1, A2 from Kp,Ki, Kd gains.
+ * - Zeros out the values in the state buffer.
+ *
+ * \par
+ * Instance structure cannot be placed into a const data section and it is recommended to use the initialization function.
+ *
+ * \par Fixed-Point Behavior
+ * Care must be taken when using the fixed-point versions of the PID Controller functions.
+ * In particular, the overflow and saturation behavior of the accumulator used in each function must be considered.
+ * Refer to the function specific documentation below for usage guidelines.

+ *
+ * Bilinear interpolation is an extension of linear interpolation applied to a two dimensional grid.
+ * The underlying function <code>f(x, y)</code> is sampled on a regular grid and the interpolation process
+ * determines values between the grid points.
+ * Bilinear interpolation is equivalent to two step linear interpolation, first in the x-dimension and then in the y-dimension.
+ * Bilinear interpolation is often used in image processing to rescale images.
+ * The CMSIS DSP library provides bilinear interpolation functions for Q7, Q15, Q31, and floating-point data types.
+ *
+ * <b>Algorithm</b>
+ * \par
+ * The instance structure used by the bilinear interpolation functions describes a two dimensional data table.
+ * For floating-point, the instance structure is defined as:
+ * <pre>
+ * typedef struct
+ * {
+ * uint16_t numRows;
+ * uint16_t numCols;
+ * float32_t *pData;
+ * } arm_bilinear_interp_instance_f32;
+ * </pre>
+ *
+ * \par
+ * where <code>numRows</code> specifies the number of rows in the table;
+ * <code>numCols</code> specifies the number of columns in the table;
+ * and <code>pData</code> points to an array of size <code>numRows*numCols</code> values.
+ * The data table <code>pTable</code> is organized in row order and the supplied data values fall on integer indexes.
+ * That is, table element (x,y) is located at <code>pTable[x + y*numCols]</code> where x and y are integers.
+ *
+ * \par
+ * Let <code>(x, y)</code> specify the desired interpolation point. Then define:
+ * <pre>
+ * XF = floor(x)
+ * YF = floor(y)
+ * </pre>
+ * \par
+ * The interpolated output point is computed as:
+ * <pre>
+ * f(x, y) = f(XF, YF) * (1-(x-XF)) * (1-(y-YF))
+ * + f(XF+1, YF) * (x-XF)*(1-(y-YF))
+ * + f(XF, YF+1) * (1-(x-XF))*(y-YF)
+ * + f(XF+1, YF+1) * (x-XF)*(y-YF)
+ * </pre>
+ * Note that the coordinates (x, y) contain integer and fractional components.
+ * The integer components specify which portion of the table to use while the
+ * fractional components control the interpolation processor.
+ *
+ * \par
+ * if (x,y) are outside of the table boundary, Bilinear interpolation returns zero output.
