| ``mx.nd.slice.axis`` |
| ======================================== |
| |
| Description |
| ---------------------- |
| |
| Slices along a given axis. |
| Returns an array slice along a given `axis` starting from the `begin` index |
| to the `end` index. |
| |
| |
| **Example**:: |
| |
| x = [[ 1., 2., 3., 4.], |
| [ 5., 6., 7., 8.], |
| [ 9., 10., 11., 12.]] |
| slice_axis(x, axis=0, begin=1, end=3) = [[ 5., 6., 7., 8.], |
| [ 9., 10., 11., 12.]] |
| slice_axis(x, axis=1, begin=0, end=2) = [[ 1., 2.], |
| [ 5., 6.], |
| [ 9., 10.]] |
| slice_axis(x, axis=1, begin=-3, end=-1) = [[ 2., 3.], |
| [ 6., 7.], |
| [ 10., 11.]] |
