Kojto	122:f9eeca106725	218	* \par Init Functions
Kojto	122:f9eeca106725	219	* There is an associated initialization function for each type of matrix
Kojto	122:f9eeca106725	220	* data structure.
Kojto	122:f9eeca106725	221	* The initialization function sets the values of the internal structure fields.
Kojto	122:f9eeca106725	222	* Refer to the function <code>arm_mat_init_f32()</code>, <code>arm_mat_init_q31()</code>
Kojto	122:f9eeca106725	223	* and <code>arm_mat_init_q15()</code> for floating-point, Q31 and Q15 types, respectively.
Kojto	122:f9eeca106725	224	*
Kojto	122:f9eeca106725	225	* \par
Kojto	122:f9eeca106725	226	* Use of the initialization function is optional. However, if initialization function is used
Kojto	122:f9eeca106725	227	* then the instance structure cannot be placed into a const data section.
Kojto	122:f9eeca106725	228	* To place the instance structure in a const data
Kojto	122:f9eeca106725	229	* section, manually initialize the data structure. For example:
Kojto	122:f9eeca106725	230	* <pre>
Kojto	122:f9eeca106725	231	* <code>arm_matrix_instance_f32 S = {nRows, nColumns, pData};</code>
Kojto	122:f9eeca106725	232	* <code>arm_matrix_instance_q31 S = {nRows, nColumns, pData};</code>
Kojto	122:f9eeca106725	233	* <code>arm_matrix_instance_q15 S = {nRows, nColumns, pData};</code>
Kojto	122:f9eeca106725	234	* </pre>
Kojto	122:f9eeca106725	235	* where <code>nRows</code> specifies the number of rows, <code>nColumns</code>
Kojto	122:f9eeca106725	236	* specifies the number of columns, and <code>pData</code> points to the
Kojto	122:f9eeca106725	237	* data array.
Kojto	122:f9eeca106725	238	*
Kojto	122:f9eeca106725	239	* \par Size Checking
Kojto	122:f9eeca106725	240	* By default all of the matrix functions perform size checking on the input and
Kojto	122:f9eeca106725	241	* output matrices. For example, the matrix addition function verifies that the
Kojto	122:f9eeca106725	242	* two input matrices and the output matrix all have the same number of rows and
Kojto	122:f9eeca106725	243	* columns. If the size check fails the functions return:
Kojto	122:f9eeca106725	244	* <pre>
Kojto	122:f9eeca106725	245	* ARM_MATH_SIZE_MISMATCH
Kojto	122:f9eeca106725	246	* </pre>
Kojto	122:f9eeca106725	247	* Otherwise the functions return
Kojto	122:f9eeca106725	248	* <pre>
Kojto	122:f9eeca106725	249	* ARM_MATH_SUCCESS
Kojto	122:f9eeca106725	250	* </pre>
Kojto	122:f9eeca106725	251	* There is some overhead associated with this matrix size checking.
Kojto	122:f9eeca106725	252	* The matrix size checking is enabled via the \#define
Kojto	122:f9eeca106725	253	* <pre>
Kojto	122:f9eeca106725	254	* ARM_MATH_MATRIX_CHECK
Kojto	122:f9eeca106725	255	* </pre>
Kojto	122:f9eeca106725	256	* within the library project settings. By default this macro is defined
Kojto	122:f9eeca106725	257	* and size checking is enabled. By changing the project settings and
Kojto	122:f9eeca106725	258	* undefining this macro size checking is eliminated and the functions
Kojto	122:f9eeca106725	259	* run a bit faster. With size checking disabled the functions always
Kojto	122:f9eeca106725	260	* return <code>ARM_MATH_SUCCESS</code>.

Kojto	122:f9eeca106725	5081	* Care must be taken when using the fixed-point versions of the PID Controller functions.
Kojto	122:f9eeca106725	5082	* In particular, the overflow and saturation behavior of the accumulator used in each function must be considered.

Kojto	122:f9eeca106725	7084	* Bilinear interpolation is an extension of linear interpolation applied to a two dimensional grid.
Kojto	122:f9eeca106725	7085	* The underlying function <code>f(x, y)</code> is sampled on a regular grid and the interpolation process
Kojto	122:f9eeca106725	7086	* determines values between the grid points.
Kojto	122:f9eeca106725	7087	* Bilinear interpolation is equivalent to two step linear interpolation, first in the x-dimension and then in the y-dimension.
Kojto	122:f9eeca106725	7088	* Bilinear interpolation is often used in image processing to rescale images.
