* There is an associated initialization function for each type of matrix

|
225
|
* data structure.
|
| ganlikun |
0:06036f8bee2d
|
226
|
* The initialization function sets the values of the internal structure fields.
|
| ganlikun |
0:06036f8bee2d
|
227
|
* Refer to the function <code>arm_mat_init_f32()</code>, <code>arm_mat_init_q31()</code>
|
| ganlikun |
0:06036f8bee2d
|
228
|
* and <code>arm_mat_init_q15()</code> for floating-point, Q31 and Q15 types, respectively.

|
* \par
|
| ganlikun |
0:06036f8bee2d
|
231
|
* Use of the initialization function is optional. However, if initialization function is used
|
| ganlikun |
0:06036f8bee2d
|
232
|
* then the instance structure cannot be placed into a const data section.
|
| ganlikun |
0:06036f8bee2d
|
233
|
* To place the instance structure in a const data
|
| ganlikun |
0:06036f8bee2d
|
234
|
* section, manually initialize the data structure. For example:
|
| ganlikun |
0:06036f8bee2d
|
235
|
* <pre>
|
| ganlikun |
0:06036f8bee2d
|
236
|
* <code>arm_matrix_instance_f32 S = {nRows, nColumns, pData};</code>
|
| ganlikun |
0:06036f8bee2d
|
237
|
* <code>arm_matrix_instance_q31 S = {nRows, nColumns, pData};</code>
|
| ganlikun |
0:06036f8bee2d
|
238
|
* <code>arm_matrix_instance_q15 S = {nRows, nColumns, pData};</code>
|
| ganlikun |
0:06036f8bee2d
|
239
|
* </pre>
|
| ganlikun |
0:06036f8bee2d
|
240
|
* where <code>nRows</code> specifies the number of rows, <code>nColumns</code>
|
| ganlikun |
0:06036f8bee2d
|
241
|
* specifies the number of columns, and <code>pData</code> points to the
|
| ganlikun |
0:06036f8bee2d
|
242
|
* data array.
|
| ganlikun |
0:06036f8bee2d
|
243
|
*
|
| ganlikun |
0:06036f8bee2d
|
244
|
* \par Size Checking
|
| ganlikun |
0:06036f8bee2d
|
245
|
* By default all of the matrix functions perform size checking on the input and
|
| ganlikun |
0:06036f8bee2d
|
246
|
* output matrices. For example, the matrix addition function verifies that the
|
| ganlikun |
0:06036f8bee2d
|
247
|
* two input matrices and the output matrix all have the same number of rows and
|
| ganlikun |
0:06036f8bee2d
|
248
|
* columns. If the size check fails the functions return:
|
| ganlikun |
0:06036f8bee2d
|
249
|
* <pre>
|
| ganlikun |
0:06036f8bee2d
|
250
|
* ARM_MATH_SIZE_MISMATCH
|
| ganlikun |
0:06036f8bee2d
|
251
|
* </pre>
|
| ganlikun |
0:06036f8bee2d
|
252
|
* Otherwise the functions return
|
| ganlikun |
0:06036f8bee2d
|
253
|
* <pre>
|
| ganlikun |
0:06036f8bee2d
|
254
|
* ARM_MATH_SUCCESS
|
| ganlikun |
0:06036f8bee2d
|
255
|
* </pre>
|
| ganlikun |
0:06036f8bee2d
|
256
|
* There is some overhead associated with this matrix size checking.
|
| ganlikun |
0:06036f8bee2d
|
257
|
* The matrix size checking is enabled via the \#define
|
| ganlikun |
0:06036f8bee2d
|
258
|
* <pre>
|
| ganlikun |
0:06036f8bee2d
|
259
|
* ARM_MATH_MATRIX_CHECK
|
| ganlikun |
0:06036f8bee2d
|
260
|
* </pre>
|
| ganlikun |
0:06036f8bee2d
|
261
|
* within the library project settings. By default this macro is defined
|
| ganlikun |
0:06036f8bee2d
|
262
|
* and size checking is enabled. By changing the project settings and
|
| ganlikun |
0:06036f8bee2d
|
263
|
* undefining this macro size checking is eliminated and the functions
|
| ganlikun |
0:06036f8bee2d
|
264
|
* run a bit faster. With size checking disabled the functions always
|
| ganlikun |
0:06036f8bee2d
|
265
|
* return <code>ARM_MATH_SUCCESS</code>.

0:06036f8bee2d

* Bilinear interpolation is equivalent to two step linear interpolation, first in the x-dimension and then in the y-dimension.
|
| ganlikun |
0:06036f8bee2d

6774
