Anna Bridge	160:5571c4ff569f	231	* Use of the initialization function is optional. However, if initialization function is used
Anna Bridge	160:5571c4ff569f	232	* then the instance structure cannot be placed into a const data section.
Anna Bridge	160:5571c4ff569f	233	* To place the instance structure in a const data
Anna Bridge	160:5571c4ff569f	234	* section, manually initialize the data structure. For example:
Anna Bridge	160:5571c4ff569f	235	* <pre>
Anna Bridge	160:5571c4ff569f	236	* <code>arm_matrix_instance_f32 S = {nRows, nColumns, pData};</code>
Anna Bridge	160:5571c4ff569f	237	* <code>arm_matrix_instance_q31 S = {nRows, nColumns, pData};</code>
Anna Bridge	160:5571c4ff569f	238	* <code>arm_matrix_instance_q15 S = {nRows, nColumns, pData};</code>
Anna Bridge	160:5571c4ff569f	239	* </pre>
Anna Bridge	160:5571c4ff569f	240	* where <code>nRows</code> specifies the number of rows, <code>nColumns</code>
Anna Bridge	160:5571c4ff569f	241	* specifies the number of columns, and <code>pData</code> points to the
Anna Bridge	160:5571c4ff569f	242	* data array.
Anna Bridge	160:5571c4ff569f	243	*
Anna Bridge	160:5571c4ff569f	244	* \par Size Checking
Anna Bridge	160:5571c4ff569f	245	* By default all of the matrix functions perform size checking on the input and
Anna Bridge	160:5571c4ff569f	246	* output matrices. For example, the matrix addition function verifies that the
Anna Bridge	160:5571c4ff569f	247	* two input matrices and the output matrix all have the same number of rows and
Anna Bridge	160:5571c4ff569f	248	* columns. If the size check fails the functions return:
Anna Bridge	160:5571c4ff569f	249	* <pre>
Anna Bridge	160:5571c4ff569f	250	* ARM_MATH_SIZE_MISMATCH
Anna Bridge	160:5571c4ff569f	251	* </pre>
Anna Bridge	160:5571c4ff569f	252	* Otherwise the functions return
Anna Bridge	160:5571c4ff569f	253	* <pre>
Anna Bridge	160:5571c4ff569f	254	* ARM_MATH_SUCCESS
Anna Bridge	160:5571c4ff569f	255	* </pre>
Anna Bridge	160:5571c4ff569f	256	* There is some overhead associated with this matrix size checking.
Anna Bridge	160:5571c4ff569f	257	* The matrix size checking is enabled via the \#define
Anna Bridge	160:5571c4ff569f	258	* <pre>
Anna Bridge	160:5571c4ff569f	259	* ARM_MATH_MATRIX_CHECK
Anna Bridge	160:5571c4ff569f	260	* </pre>
Anna Bridge	160:5571c4ff569f	261	* within the library project settings. By default this macro is defined
Anna Bridge	160:5571c4ff569f	262	* and size checking is enabled. By changing the project settings and
Anna Bridge	160:5571c4ff569f	263	* undefining this macro size checking is eliminated and the functions
Anna Bridge	160:5571c4ff569f	264	* run a bit faster. With size checking disabled the functions always
Anna Bridge	160:5571c4ff569f	265	* return <code>ARM_MATH_SUCCESS</code>.

Anna Bridge	160:5571c4ff569f	4785	* The initialization function performs the following operations:

Anna Bridge	160:5571c4ff569f	5407	* Linear interpolation works by effectively drawing a straight line between two neighboring samples and returning the appropriate point along that line

Anna Bridge	160:5571c4ff569f	6703	* Bilinear interpolation is an extension of linear interpolation applied to a two dimensional grid.
Anna Bridge	160:5571c4ff569f	6704	* The underlying function <code>f(x, y)</code> is sampled on a regular grid and the interpolation process
Anna Bridge	160:5571c4ff569f	6705	* determines values between the grid points.
Anna Bridge	160:5571c4ff569f	6706	* Bilinear interpolation is equivalent to two step linear interpolation, first in the x-dimension and then in the y-dimension.
Anna Bridge	160:5571c4ff569f	6707	* Bilinear interpolation is often used in image processing to rescale images.
Anna Bridge	160:5571c4ff569f	6708	* The CMSIS DSP library provides bilinear interpolation functions for Q7, Q15, Q31, and floating-point data types.
