mbed_official	25:ac5b0a371348	226	* Use of the initialization function is optional. However, if initialization function is used

mbed_official	25:ac5b0a371348	228	* To place the instance structure in a const data
mbed_official	25:ac5b0a371348	229	* section, manually initialize the data structure. For example:
mbed_official	25:ac5b0a371348	230	* <pre>
mbed_official	25:ac5b0a371348	231	* <code>arm_matrix_instance_f32 S = {nRows, nColumns, pData};</code>
mbed_official	25:ac5b0a371348	232	* <code>arm_matrix_instance_q31 S = {nRows, nColumns, pData};</code>

mbed_official	25:ac5b0a371348	234	* </pre>
mbed_official	25:ac5b0a371348	235	* where <code>nRows</code> specifies the number of rows, <code>nColumns</code>

mbed_official	25:ac5b0a371348	239	* \par Size Checking
mbed_official	25:ac5b0a371348	240	* By default all of the matrix functions perform size checking on the input and
mbed_official	25:ac5b0a371348	241	* output matrices. For example, the matrix addition function verifies that the
mbed_official	25:ac5b0a371348	242	* two input matrices and the output matrix all have the same number of rows and
mbed_official	25:ac5b0a371348	243	* columns. If the size check fails the functions return:
mbed_official	25:ac5b0a371348	244	* <pre>
mbed_official	25:ac5b0a371348	245	* ARM_MATH_SIZE_MISMATCH
mbed_official	25:ac5b0a371348	246	* </pre>
mbed_official	25:ac5b0a371348	247	* Otherwise the functions return
mbed_official	25:ac5b0a371348	248	* <pre>
mbed_official	25:ac5b0a371348	249	* ARM_MATH_SUCCESS
mbed_official	25:ac5b0a371348	250	* </pre>
mbed_official	25:ac5b0a371348	251	* There is some overhead associated with this matrix size checking.
mbed_official	25:ac5b0a371348	252	* The matrix size checking is enabled via the \#define
mbed_official	25:ac5b0a371348	253	* <pre>
mbed_official	25:ac5b0a371348	254	* ARM_MATH_MATRIX_CHECK
mbed_official	25:ac5b0a371348	255	* </pre>
mbed_official	25:ac5b0a371348	256	* within the library project settings. By default this macro is defined
mbed_official	25:ac5b0a371348	257	* and size checking is enabled. By changing the project settings and
mbed_official	25:ac5b0a371348	258	* undefining this macro size checking is eliminated and the functions
mbed_official	25:ac5b0a371348	259	* run a bit faster. With size checking disabled the functions always
mbed_official	25:ac5b0a371348	260	* return <code>ARM_MATH_SUCCESS</code>.

mbed_official	25:ac5b0a371348	6070	* There are separate functions for Q15, Q31, and floating-point data types.
mbed_official	25:ac5b0a371348	6071	* The square root function is computed using the Newton-Raphson algorithm.
mbed_official	25:ac5b0a371348	6072	* This is an iterative algorithm of the form:

mbed_official	25:ac5b0a371348	6079	* For the square root function, the algorithm reduces to:
mbed_official	25:ac5b0a371348	6080	* <pre>
mbed_official	25:ac5b0a371348	6081	* x0 = in/2 [initial guess]

mbed_official	25:ac5b0a371348	7084	* Bilinear interpolation is an extension of linear interpolation applied to a two dimensional grid.
mbed_official	25:ac5b0a371348	7085	* The underlying function <code>f(x, y)</code> is sampled on a regular grid and the interpolation process
mbed_official	25:ac5b0a371348	7086	* determines values between the grid points.
mbed_official	25:ac5b0a371348	7087	* Bilinear interpolation is equivalent to two step linear interpolation, first in the x-dimension and then in the y-dimension.
mbed_official	25:ac5b0a371348	7088	* Bilinear interpolation is often used in image processing to rescale images.
