AnnaBridge	157:e7ca05fa8600	203	* definition for the floating-point matrix structure is shown

AnnaBridge	157:e7ca05fa8600	232	* then the instance structure cannot be placed into a const data section.
AnnaBridge	157:e7ca05fa8600	233	* To place the instance structure in a const data
AnnaBridge	157:e7ca05fa8600	234	* section, manually initialize the data structure. For example:
AnnaBridge	157:e7ca05fa8600	235	* <pre>
AnnaBridge	157:e7ca05fa8600	236	* <code>arm_matrix_instance_f32 S = {nRows, nColumns, pData};</code>
AnnaBridge	157:e7ca05fa8600	237	* <code>arm_matrix_instance_q31 S = {nRows, nColumns, pData};</code>
AnnaBridge	157:e7ca05fa8600	238	* <code>arm_matrix_instance_q15 S = {nRows, nColumns, pData};</code>
AnnaBridge	157:e7ca05fa8600	239	* </pre>
AnnaBridge	157:e7ca05fa8600	240	* where <code>nRows</code> specifies the number of rows, <code>nColumns</code>
AnnaBridge	157:e7ca05fa8600	241	* specifies the number of columns, and <code>pData</code> points to the
AnnaBridge	157:e7ca05fa8600	242	* data array.
AnnaBridge	157:e7ca05fa8600	243	*
AnnaBridge	157:e7ca05fa8600	244	* \par Size Checking
AnnaBridge	157:e7ca05fa8600	245	* By default all of the matrix functions perform size checking on the input and
AnnaBridge	157:e7ca05fa8600	246	* output matrices. For example, the matrix addition function verifies that the
AnnaBridge	157:e7ca05fa8600	247	* two input matrices and the output matrix all have the same number of rows and
AnnaBridge	157:e7ca05fa8600	248	* columns. If the size check fails the functions return:
AnnaBridge	157:e7ca05fa8600	249	* <pre>
AnnaBridge	157:e7ca05fa8600	250	* ARM_MATH_SIZE_MISMATCH
AnnaBridge	157:e7ca05fa8600	251	* </pre>
AnnaBridge	157:e7ca05fa8600	252	* Otherwise the functions return
AnnaBridge	157:e7ca05fa8600	253	* <pre>
AnnaBridge	157:e7ca05fa8600	254	* ARM_MATH_SUCCESS
AnnaBridge	157:e7ca05fa8600	255	* </pre>
AnnaBridge	157:e7ca05fa8600	256	* There is some overhead associated with this matrix size checking.
AnnaBridge	157:e7ca05fa8600	257	* The matrix size checking is enabled via the \#define
AnnaBridge	157:e7ca05fa8600	258	* <pre>
AnnaBridge	157:e7ca05fa8600	259	* ARM_MATH_MATRIX_CHECK
AnnaBridge	157:e7ca05fa8600	260	* </pre>
AnnaBridge	157:e7ca05fa8600	261	* within the library project settings. By default this macro is defined
AnnaBridge	157:e7ca05fa8600	262	* and size checking is enabled. By changing the project settings and
AnnaBridge	157:e7ca05fa8600	263	* undefining this macro size checking is eliminated and the functions
AnnaBridge	157:e7ca05fa8600	264	* run a bit faster. With size checking disabled the functions always
AnnaBridge	157:e7ca05fa8600	265	* return <code>ARM_MATH_SUCCESS</code>.

AnnaBridge	157:e7ca05fa8600	6703	* Bilinear interpolation is an extension of linear interpolation applied to a two dimensional grid.
AnnaBridge	157:e7ca05fa8600	6704	* The underlying function <code>f(x, y)</code> is sampled on a regular grid and the interpolation process
AnnaBridge	157:e7ca05fa8600	6705	* determines values between the grid points.
AnnaBridge	157:e7ca05fa8600	6706	* Bilinear interpolation is equivalent to two step linear interpolation, first in the x-dimension and then in the y-dimension.
AnnaBridge	157:e7ca05fa8600	6707	* Bilinear interpolation is often used in image processing to rescale images.
AnnaBridge	157:e7ca05fa8600	6708	* The CMSIS DSP library provides bilinear interpolation functions for Q7, Q15, Q31, and floating-point data types.
