Kojto	115:87f2f5183dfb	223	* \par Init Functions
Kojto	115:87f2f5183dfb	224	* There is an associated initialization function for each type of matrix
Kojto	115:87f2f5183dfb	225	* data structure.
Kojto	115:87f2f5183dfb	226	* The initialization function sets the values of the internal structure fields.
Kojto	115:87f2f5183dfb	227	* Refer to the function <code>arm_mat_init_f32()</code>, <code>arm_mat_init_q31()</code>
Kojto	115:87f2f5183dfb	228	* and <code>arm_mat_init_q15()</code> for floating-point, Q31 and Q15 types, respectively.
Kojto	115:87f2f5183dfb	229	*
Kojto	115:87f2f5183dfb	230	* \par
Kojto	115:87f2f5183dfb	231	* Use of the initialization function is optional. However, if initialization function is used
Kojto	115:87f2f5183dfb	232	* then the instance structure cannot be placed into a const data section.
Kojto	115:87f2f5183dfb	233	* To place the instance structure in a const data
Kojto	115:87f2f5183dfb	234	* section, manually initialize the data structure. For example:
Kojto	115:87f2f5183dfb	235	* <pre>
Kojto	115:87f2f5183dfb	236	* <code>arm_matrix_instance_f32 S = {nRows, nColumns, pData};</code>
Kojto	115:87f2f5183dfb	237	* <code>arm_matrix_instance_q31 S = {nRows, nColumns, pData};</code>
Kojto	115:87f2f5183dfb	238	* <code>arm_matrix_instance_q15 S = {nRows, nColumns, pData};</code>
Kojto	115:87f2f5183dfb	239	* </pre>
Kojto	115:87f2f5183dfb	240	* where <code>nRows</code> specifies the number of rows, <code>nColumns</code>
Kojto	115:87f2f5183dfb	241	* specifies the number of columns, and <code>pData</code> points to the
Kojto	115:87f2f5183dfb	242	* data array.
Kojto	115:87f2f5183dfb	243	*
Kojto	115:87f2f5183dfb	244	* \par Size Checking
Kojto	115:87f2f5183dfb	245	* By default all of the matrix functions perform size checking on the input and
Kojto	115:87f2f5183dfb	246	* output matrices. For example, the matrix addition function verifies that the
Kojto	115:87f2f5183dfb	247	* two input matrices and the output matrix all have the same number of rows and
Kojto	115:87f2f5183dfb	248	* columns. If the size check fails the functions return:
Kojto	115:87f2f5183dfb	249	* <pre>
Kojto	115:87f2f5183dfb	250	* ARM_MATH_SIZE_MISMATCH
Kojto	115:87f2f5183dfb	251	* </pre>
Kojto	115:87f2f5183dfb	252	* Otherwise the functions return
Kojto	115:87f2f5183dfb	253	* <pre>
Kojto	115:87f2f5183dfb	254	* ARM_MATH_SUCCESS
Kojto	115:87f2f5183dfb	255	* </pre>
Kojto	115:87f2f5183dfb	256	* There is some overhead associated with this matrix size checking.
Kojto	115:87f2f5183dfb	257	* The matrix size checking is enabled via the \#define
Kojto	115:87f2f5183dfb	258	* <pre>
Kojto	115:87f2f5183dfb	259	* ARM_MATH_MATRIX_CHECK
Kojto	115:87f2f5183dfb	260	* </pre>
Kojto	115:87f2f5183dfb	261	* within the library project settings. By default this macro is defined
Kojto	115:87f2f5183dfb	262	* and size checking is enabled. By changing the project settings and
Kojto	115:87f2f5183dfb	263	* undefining this macro size checking is eliminated and the functions
Kojto	115:87f2f5183dfb	264	* run a bit faster. With size checking disabled the functions always
Kojto	115:87f2f5183dfb	265	* return <code>ARM_MATH_SUCCESS</code>.

Kojto	115:87f2f5183dfb	4853	* - Initializes the Gains A0, A1, A2 from Kp,Ki, Kd gains.
Kojto	115:87f2f5183dfb	4854	* - Zeros out the values in the state buffer.

Kojto	115:87f2f5183dfb	4860	* Care must be taken when using the fixed-point versions of the PID Controller functions.
Kojto	115:87f2f5183dfb	4861	* In particular, the overflow and saturation behavior of the accumulator used in each function must be considered.

Kojto	115:87f2f5183dfb	6770	* Bilinear interpolation is an extension of linear interpolation applied to a two dimensional grid.
Kojto	115:87f2f5183dfb	6771	* The underlying function <code>f(x, y)</code> is sampled on a regular grid and the interpolation process
Kojto	115:87f2f5183dfb	6772	* determines values between the grid points.
Kojto	115:87f2f5183dfb	6773	* Bilinear interpolation is equivalent to two step linear interpolation, first in the x-dimension and then in the y-dimension.
Kojto	115:87f2f5183dfb	6774	* Bilinear interpolation is often used in image processing to rescale images.
