AnnaBridge 156:ff21514d8981 51 * 32-bit integer and 32-bit floating-point values.
AnnaBridge 156:ff21514d8981 52 *

AnnaBridge 156:ff21514d8981 200 * This set of functions provides basic matrix math operations.
AnnaBridge 156:ff21514d8981 201 * The functions operate on matrix data structures. For example,
AnnaBridge 156:ff21514d8981 202 * the type
AnnaBridge 156:ff21514d8981 203 * definition for the floating-point matrix structure is shown
AnnaBridge 156:ff21514d8981 204 * below:
AnnaBridge 156:ff21514d8981 205 * <pre>
AnnaBridge 156:ff21514d8981 206 * typedef struct
AnnaBridge 156:ff21514d8981 207 * {
AnnaBridge 156:ff21514d8981 208 * uint16_t numRows; // number of rows of the matrix.
AnnaBridge 156:ff21514d8981 209 * uint16_t numCols; // number of columns of the matrix.

AnnaBridge 156:ff21514d8981 211 * } arm_matrix_instance_f32;
AnnaBridge 156:ff21514d8981 212 * </pre>
AnnaBridge 156:ff21514d8981 213 * There are similar definitions for Q15 and Q31 data types.
AnnaBridge 156:ff21514d8981 214 *
AnnaBridge 156:ff21514d8981 215 * The structure specifies the size of the matrix and then points to
AnnaBridge 156:ff21514d8981 216 * an array of data. The array is of size <code>numRows X numCols</code>
AnnaBridge 156:ff21514d8981 217 * and the values are arranged in row order. That is, the

AnnaBridge 156:ff21514d8981 221 * </pre>
AnnaBridge 156:ff21514d8981 222 *
AnnaBridge 156:ff21514d8981 223 * \par Init Functions
AnnaBridge 156:ff21514d8981 224 * There is an associated initialization function for each type of matrix
AnnaBridge 156:ff21514d8981 225 * data structure.
AnnaBridge 156:ff21514d8981 226 * The initialization function sets the values of the internal structure fields.
AnnaBridge 156:ff21514d8981 227 * Refer to the function <code>arm_mat_init_f32()</code>, <code>arm_mat_init_q31()</code>
AnnaBridge 156:ff21514d8981 228 * and <code>arm_mat_init_q15()</code> for floating-point, Q31 and Q15 types, respectively.
AnnaBridge 156:ff21514d8981 229 *
AnnaBridge 156:ff21514d8981 230 * \par
AnnaBridge 156:ff21514d8981 231 * Use of the initialization function is optional. However, if initialization function is used
AnnaBridge 156:ff21514d8981 232 * then the instance structure cannot be placed into a const data section.
AnnaBridge 156:ff21514d8981 233 * To place the instance structure in a const data
AnnaBridge 156:ff21514d8981 234 * section, manually initialize the data structure. For example:
AnnaBridge 156:ff21514d8981 235 * <pre>
AnnaBridge 156:ff21514d8981 236 * <code>arm_matrix_instance_f32 S = {nRows, nColumns, pData};</code>
AnnaBridge 156:ff21514d8981 237 * <code>arm_matrix_instance_q31 S = {nRows, nColumns, pData};</code>
AnnaBridge 156:ff21514d8981 238 * <code>arm_matrix_instance_q15 S = {nRows, nColumns, pData};</code>
AnnaBridge 156:ff21514d8981 239 * </pre>
AnnaBridge 156:ff21514d8981 240 * where <code>nRows</code> specifies the number of rows, <code>nColumns</code>
AnnaBridge 156:ff21514d8981 241 * specifies the number of columns, and <code>pData</code> points to the
AnnaBridge 156:ff21514d8981 242 * data array.
AnnaBridge 156:ff21514d8981 243 *
AnnaBridge 156:ff21514d8981 244 * \par Size Checking
AnnaBridge 156:ff21514d8981 245 * By default all of the matrix functions perform size checking on the input and
AnnaBridge 156:ff21514d8981 246 * output matrices. For example, the matrix addition function verifies that the
AnnaBridge 156:ff21514d8981 247 * two input matrices and the output matrix all have the same number of rows and
AnnaBridge 156:ff21514d8981 248 * columns. If the size check fails the functions return:
AnnaBridge 156:ff21514d8981 249 * <pre>
AnnaBridge 156:ff21514d8981 250 * ARM_MATH_SIZE_MISMATCH
AnnaBridge 156:ff21514d8981 251 * </pre>
AnnaBridge 156:ff21514d8981 252 * Otherwise the functions return
AnnaBridge 156:ff21514d8981 253 * <pre>
AnnaBridge 156:ff21514d8981 254 * ARM_MATH_SUCCESS
AnnaBridge 156:ff21514d8981 255 * </pre>
AnnaBridge 156:ff21514d8981 256 * There is some overhead associated with this matrix size checking.
AnnaBridge 156:ff21514d8981 257 * The matrix size checking is enabled via the \#define
AnnaBridge 156:ff21514d8981 258 * <pre>
AnnaBridge 156:ff21514d8981 259 * ARM_MATH_MATRIX_CHECK
AnnaBridge 156:ff21514d8981 260 * </pre>
AnnaBridge 156:ff21514d8981 261 * within the library project settings. By default this macro is defined
AnnaBridge 156:ff21514d8981 262 * and size checking is enabled. By changing the project settings and
AnnaBridge 156:ff21514d8981 263 * undefining this macro size checking is eliminated and the functions
AnnaBridge 156:ff21514d8981 264 * run a bit faster. With size checking disabled the functions always
AnnaBridge 156:ff21514d8981 265 * return <code>ARM_MATH_SUCCESS</code>.

AnnaBridge 156:ff21514d8981 6703 * Bilinear interpolation is an extension of linear interpolation applied to a two dimensional grid.
AnnaBridge 156:ff21514d8981 6704 * The underlying function <code>f(x, y)</code> is sampled on a regular grid and the interpolation process
AnnaBridge 156:ff21514d8981 6705 * determines values between the grid points.
AnnaBridge 156:ff21514d8981 6706 * Bilinear interpolation is equivalent to two step linear interpolation, first in the x-dimension and then in the y-dimension.
AnnaBridge 156:ff21514d8981 6707 * Bilinear interpolation is often used in image processing to rescale images.
AnnaBridge 156:ff21514d8981 6708 * The CMSIS DSP library provides bilinear interpolation functions for Q7, Q15, Q31, and floating-point data types.
