sahilmgandhi	18:6a4db94011d3	218	* \par Init Functions
sahilmgandhi	18:6a4db94011d3	219	* There is an associated initialization function for each type of matrix
sahilmgandhi	18:6a4db94011d3	220	* data structure.
sahilmgandhi	18:6a4db94011d3	221	* The initialization function sets the values of the internal structure fields.
sahilmgandhi	18:6a4db94011d3	222	* Refer to the function <code>arm_mat_init_f32()</code>, <code>arm_mat_init_q31()</code>
sahilmgandhi	18:6a4db94011d3	223	* and <code>arm_mat_init_q15()</code> for floating-point, Q31 and Q15 types, respectively.
sahilmgandhi	18:6a4db94011d3	224	*
sahilmgandhi	18:6a4db94011d3	225	* \par
sahilmgandhi	18:6a4db94011d3	226	* Use of the initialization function is optional. However, if initialization function is used
sahilmgandhi	18:6a4db94011d3	227	* then the instance structure cannot be placed into a const data section.
sahilmgandhi	18:6a4db94011d3	228	* To place the instance structure in a const data
sahilmgandhi	18:6a4db94011d3	229	* section, manually initialize the data structure. For example:
sahilmgandhi	18:6a4db94011d3	230	* <pre>
sahilmgandhi	18:6a4db94011d3	231	* <code>arm_matrix_instance_f32 S = {nRows, nColumns, pData};</code>
sahilmgandhi	18:6a4db94011d3	232	* <code>arm_matrix_instance_q31 S = {nRows, nColumns, pData};</code>
sahilmgandhi	18:6a4db94011d3	233	* <code>arm_matrix_instance_q15 S = {nRows, nColumns, pData};</code>
sahilmgandhi	18:6a4db94011d3	234	* </pre>
sahilmgandhi	18:6a4db94011d3	235	* where <code>nRows</code> specifies the number of rows, <code>nColumns</code>
sahilmgandhi	18:6a4db94011d3	236	* specifies the number of columns, and <code>pData</code> points to the
sahilmgandhi	18:6a4db94011d3	237	* data array.
sahilmgandhi	18:6a4db94011d3	238	*
sahilmgandhi	18:6a4db94011d3	239	* \par Size Checking
sahilmgandhi	18:6a4db94011d3	240	* By default all of the matrix functions perform size checking on the input and
sahilmgandhi	18:6a4db94011d3	241	* output matrices. For example, the matrix addition function verifies that the
sahilmgandhi	18:6a4db94011d3	242	* two input matrices and the output matrix all have the same number of rows and
sahilmgandhi	18:6a4db94011d3	243	* columns. If the size check fails the functions return:
sahilmgandhi	18:6a4db94011d3	244	* <pre>
sahilmgandhi	18:6a4db94011d3	245	* ARM_MATH_SIZE_MISMATCH
sahilmgandhi	18:6a4db94011d3	246	* </pre>
sahilmgandhi	18:6a4db94011d3	247	* Otherwise the functions return
sahilmgandhi	18:6a4db94011d3	248	* <pre>
sahilmgandhi	18:6a4db94011d3	249	* ARM_MATH_SUCCESS
sahilmgandhi	18:6a4db94011d3	250	* </pre>
sahilmgandhi	18:6a4db94011d3	251	* There is some overhead associated with this matrix size checking.
sahilmgandhi	18:6a4db94011d3	252	* The matrix size checking is enabled via the \#define
sahilmgandhi	18:6a4db94011d3	253	* <pre>
sahilmgandhi	18:6a4db94011d3	254	* ARM_MATH_MATRIX_CHECK
sahilmgandhi	18:6a4db94011d3	255	* </pre>
sahilmgandhi	18:6a4db94011d3	256	* within the library project settings. By default this macro is defined
sahilmgandhi	18:6a4db94011d3	257	* and size checking is enabled. By changing the project settings and
sahilmgandhi	18:6a4db94011d3	258	* undefining this macro size checking is eliminated and the functions
sahilmgandhi	18:6a4db94011d3	259	* run a bit faster. With size checking disabled the functions always
sahilmgandhi	18:6a4db94011d3	260	* return <code>ARM_MATH_SUCCESS</code>.

sahilmgandhi	18:6a4db94011d3	5060	* the integral value determines the reaction based on the sum of recent errors,

sahilmgandhi	18:6a4db94011d3	5064	* The Gains A0, A1, A2 and state variables for a PID controller are stored together in an instance data structure.
sahilmgandhi	18:6a4db94011d3	5065	* A separate instance structure must be defined for each PID Controller.

sahilmgandhi	18:6a4db94011d3	5071	* \par Initialization Functions
sahilmgandhi	18:6a4db94011d3	5072	* There is also an associated initialization function for each data type.
sahilmgandhi	18:6a4db94011d3	5073	* The initialization function performs the following operations:
sahilmgandhi	18:6a4db94011d3	5074	* - Initializes the Gains A0, A1, A2 from Kp,Ki, Kd gains.
sahilmgandhi	18:6a4db94011d3	5075	* - Zeros out the values in the state buffer.

sahilmgandhi	18:6a4db94011d3	5080	* \par Fixed-Point Behavior
sahilmgandhi	18:6a4db94011d3	5081	* Care must be taken when using the fixed-point versions of the PID Controller functions.
sahilmgandhi	18:6a4db94011d3	5082	* In particular, the overflow and saturation behavior of the accumulator used in each function must be considered.

sahilmgandhi	18:6a4db94011d3	7084	* Bilinear interpolation is an extension of linear interpolation applied to a two dimensional grid.
sahilmgandhi	18:6a4db94011d3	7085	* The underlying function <code>f(x, y)</code> is sampled on a regular grid and the interpolation process
sahilmgandhi	18:6a4db94011d3	7086	* determines values between the grid points.
sahilmgandhi	18:6a4db94011d3	7087	* Bilinear interpolation is equivalent to two step linear interpolation, first in the x-dimension and then in the y-dimension.
sahilmgandhi	18:6a4db94011d3	7088	* Bilinear interpolation is often used in image processing to rescale images.
sahilmgandhi	18:6a4db94011d3	7089	* The CMSIS DSP library provides bilinear interpolation functions for Q7, Q15, Q31, and floating-point data types.
