ganlikun	0:20e0c61e0684	231	* Use of the initialization function is optional. However, if initialization function is used
ganlikun	0:20e0c61e0684	232	* then the instance structure cannot be placed into a const data section.
ganlikun	0:20e0c61e0684	233	* To place the instance structure in a const data
ganlikun	0:20e0c61e0684	234	* section, manually initialize the data structure. For example:
ganlikun	0:20e0c61e0684	235	* <pre>
ganlikun	0:20e0c61e0684	236	* <code>arm_matrix_instance_f32 S = {nRows, nColumns, pData};</code>

ganlikun	0:20e0c61e0684	239	* </pre>
ganlikun	0:20e0c61e0684	240	* where <code>nRows</code> specifies the number of rows, <code>nColumns</code>

ganlikun	0:20e0c61e0684	244	* \par Size Checking
ganlikun	0:20e0c61e0684	245	* By default all of the matrix functions perform size checking on the input and
ganlikun	0:20e0c61e0684	246	* output matrices. For example, the matrix addition function verifies that the
ganlikun	0:20e0c61e0684	247	* two input matrices and the output matrix all have the same number of rows and
ganlikun	0:20e0c61e0684	248	* columns. If the size check fails the functions return:
ganlikun	0:20e0c61e0684	249	* <pre>
ganlikun	0:20e0c61e0684	250	* ARM_MATH_SIZE_MISMATCH
ganlikun	0:20e0c61e0684	251	* </pre>
ganlikun	0:20e0c61e0684	252	* Otherwise the functions return
ganlikun	0:20e0c61e0684	253	* <pre>
ganlikun	0:20e0c61e0684	254	* ARM_MATH_SUCCESS
ganlikun	0:20e0c61e0684	255	* </pre>
ganlikun	0:20e0c61e0684	256	* There is some overhead associated with this matrix size checking.
ganlikun	0:20e0c61e0684	257	* The matrix size checking is enabled via the \#define
ganlikun	0:20e0c61e0684	258	* <pre>
ganlikun	0:20e0c61e0684	259	* ARM_MATH_MATRIX_CHECK
ganlikun	0:20e0c61e0684	260	* </pre>
ganlikun	0:20e0c61e0684	261	* within the library project settings. By default this macro is defined
ganlikun	0:20e0c61e0684	262	* and size checking is enabled. By changing the project settings and
ganlikun	0:20e0c61e0684	263	* undefining this macro size checking is eliminated and the functions
ganlikun	0:20e0c61e0684	264	* run a bit faster. With size checking disabled the functions always
ganlikun	0:20e0c61e0684	265	* return <code>ARM_MATH_SUCCESS</code>.

ganlikun	0:20e0c61e0684	6770	* Bilinear interpolation is an extension of linear interpolation applied to a two dimensional grid.

ganlikun	0:20e0c61e0684	6773	* Bilinear interpolation is equivalent to two step linear interpolation, first in the x-dimension and then in the y-dimension.
ganlikun	0:20e0c61e0684	6774	* Bilinear interpolation is often used in image processing to rescale images.
