Kojto	110:165afa46840b	229	* section, manually initialize the data structure. For example:
Kojto	110:165afa46840b	230	* <pre>
Kojto	110:165afa46840b	231	* <code>arm_matrix_instance_f32 S = {nRows, nColumns, pData};</code>
Kojto	110:165afa46840b	232	* <code>arm_matrix_instance_q31 S = {nRows, nColumns, pData};</code>
Kojto	110:165afa46840b	233	* <code>arm_matrix_instance_q15 S = {nRows, nColumns, pData};</code>
Kojto	110:165afa46840b	234	* </pre>
Kojto	110:165afa46840b	235	* where <code>nRows</code> specifies the number of rows, <code>nColumns</code>
Kojto	110:165afa46840b	236	* specifies the number of columns, and <code>pData</code> points to the
Kojto	110:165afa46840b	237	* data array.
Kojto	110:165afa46840b	238	*
Kojto	110:165afa46840b	239	* \par Size Checking
Kojto	110:165afa46840b	240	* By default all of the matrix functions perform size checking on the input and
Kojto	110:165afa46840b	241	* output matrices. For example, the matrix addition function verifies that the
Kojto	110:165afa46840b	242	* two input matrices and the output matrix all have the same number of rows and
Kojto	110:165afa46840b	243	* columns. If the size check fails the functions return:
Kojto	110:165afa46840b	244	* <pre>
Kojto	110:165afa46840b	245	* ARM_MATH_SIZE_MISMATCH
Kojto	110:165afa46840b	246	* </pre>
Kojto	110:165afa46840b	247	* Otherwise the functions return
Kojto	110:165afa46840b	248	* <pre>
Kojto	110:165afa46840b	249	* ARM_MATH_SUCCESS
Kojto	110:165afa46840b	250	* </pre>
Kojto	110:165afa46840b	251	* There is some overhead associated with this matrix size checking.
Kojto	110:165afa46840b	252	* The matrix size checking is enabled via the \#define
Kojto	110:165afa46840b	253	* <pre>
Kojto	110:165afa46840b	254	* ARM_MATH_MATRIX_CHECK
Kojto	110:165afa46840b	255	* </pre>
Kojto	110:165afa46840b	256	* within the library project settings. By default this macro is defined
Kojto	110:165afa46840b	257	* and size checking is enabled. By changing the project settings and
Kojto	110:165afa46840b	258	* undefining this macro size checking is eliminated and the functions
Kojto	110:165afa46840b	259	* run a bit faster. With size checking disabled the functions always
Kojto	110:165afa46840b	260	* return <code>ARM_MATH_SUCCESS</code>.

Kojto	110:165afa46840b	5073	* The initialization function performs the following operations:
Kojto	110:165afa46840b	5074	* - Initializes the Gains A0, A1, A2 from Kp,Ki, Kd gains.
Kojto	110:165afa46840b	5075	* - Zeros out the values in the state buffer.

Kojto	110:165afa46840b	5081	* Care must be taken when using the fixed-point versions of the PID Controller functions.
Kojto	110:165afa46840b	5082	* In particular, the overflow and saturation behavior of the accumulator used in each function must be considered.

Kojto	110:165afa46840b	7084	* Bilinear interpolation is an extension of linear interpolation applied to a two dimensional grid.
Kojto	110:165afa46840b	7085	* The underlying function <code>f(x, y)</code> is sampled on a regular grid and the interpolation process
Kojto	110:165afa46840b	7086	* determines values between the grid points.
Kojto	110:165afa46840b	7087	* Bilinear interpolation is equivalent to two step linear interpolation, first in the x-dimension and then in the y-dimension.
Kojto	110:165afa46840b	7088	* Bilinear interpolation is often used in image processing to rescale images.
