AnnaBridge	143:86740a56073b	228	* To place the instance structure in a const data
AnnaBridge	143:86740a56073b	229	* section, manually initialize the data structure. For example:
AnnaBridge	143:86740a56073b	230	* <pre>
AnnaBridge	143:86740a56073b	231	* <code>arm_matrix_instance_f32 S = {nRows, nColumns, pData};</code>
AnnaBridge	143:86740a56073b	232	* <code>arm_matrix_instance_q31 S = {nRows, nColumns, pData};</code>

AnnaBridge	143:86740a56073b	234	* </pre>
AnnaBridge	143:86740a56073b	235	* where <code>nRows</code> specifies the number of rows, <code>nColumns</code>
AnnaBridge	143:86740a56073b	236	* specifies the number of columns, and <code>pData</code> points to the

AnnaBridge	143:86740a56073b	239	* \par Size Checking
AnnaBridge	143:86740a56073b	240	* By default all of the matrix functions perform size checking on the input and
AnnaBridge	143:86740a56073b	241	* output matrices. For example, the matrix addition function verifies that the
AnnaBridge	143:86740a56073b	242	* two input matrices and the output matrix all have the same number of rows and
AnnaBridge	143:86740a56073b	243	* columns. If the size check fails the functions return:
AnnaBridge	143:86740a56073b	244	* <pre>
AnnaBridge	143:86740a56073b	245	* ARM_MATH_SIZE_MISMATCH
AnnaBridge	143:86740a56073b	246	* </pre>
AnnaBridge	143:86740a56073b	247	* Otherwise the functions return
AnnaBridge	143:86740a56073b	248	* <pre>
AnnaBridge	143:86740a56073b	249	* ARM_MATH_SUCCESS
AnnaBridge	143:86740a56073b	250	* </pre>
AnnaBridge	143:86740a56073b	251	* There is some overhead associated with this matrix size checking.
AnnaBridge	143:86740a56073b	252	* The matrix size checking is enabled via the \#define
AnnaBridge	143:86740a56073b	253	* <pre>
AnnaBridge	143:86740a56073b	254	* ARM_MATH_MATRIX_CHECK
AnnaBridge	143:86740a56073b	255	* </pre>
AnnaBridge	143:86740a56073b	256	* within the library project settings. By default this macro is defined
AnnaBridge	143:86740a56073b	257	* and size checking is enabled. By changing the project settings and
AnnaBridge	143:86740a56073b	258	* undefining this macro size checking is eliminated and the functions
AnnaBridge	143:86740a56073b	259	* run a bit faster. With size checking disabled the functions always
AnnaBridge	143:86740a56073b	260	* return <code>ARM_MATH_SUCCESS</code>.

AnnaBridge	143:86740a56073b	6068	*
AnnaBridge	143:86740a56073b	6069	* Computes the square root of a number.
AnnaBridge	143:86740a56073b	6070	* There are separate functions for Q15, Q31, and floating-point data types.
AnnaBridge	143:86740a56073b	6071	* The square root function is computed using the Newton-Raphson algorithm.
AnnaBridge	143:86740a56073b	6072	* This is an iterative algorithm of the form:
AnnaBridge	143:86740a56073b	6073	* <pre>
AnnaBridge	143:86740a56073b	6074	* x1 = x0 - f(x0)/f'(x0)

AnnaBridge	143:86740a56073b	6078	* <code>f'(x0)</code> is the derivative of <code>f()</code> evaluated at <code>x0</code>.
AnnaBridge	143:86740a56073b	6079	* For the square root function, the algorithm reduces to:
AnnaBridge	143:86740a56073b	6080	* <pre>
AnnaBridge	143:86740a56073b	6081	* x0 = in/2 [initial guess]

AnnaBridge	143:86740a56073b	7084	* Bilinear interpolation is an extension of linear interpolation applied to a two dimensional grid.
AnnaBridge	143:86740a56073b	7085	* The underlying function <code>f(x, y)</code> is sampled on a regular grid and the interpolation process
AnnaBridge	143:86740a56073b	7086	* determines values between the grid points.
AnnaBridge	143:86740a56073b	7087	* Bilinear interpolation is equivalent to two step linear interpolation, first in the x-dimension and then in the y-dimension.
AnnaBridge	143:86740a56073b	7088	* Bilinear interpolation is often used in image processing to rescale images.
AnnaBridge	143:86740a56073b	7089	* The CMSIS DSP library provides bilinear interpolation functions for Q7, Q15, Q31, and floating-point data types.
