| ``mx.symbol.broadcast_axes`` |
| ======================================================== |
| |
| Description |
| ---------------------- |
| |
| Broadcasts the input array over particular axes. |
| |
| Broadcasting is allowed on axes with size 1, such as from `(2,1,3,1)` to |
| `(2,8,3,9)`. Elements will be duplicated on the broadcasted axes. |
| |
| `broadcast_axes` is an alias to the function `broadcast_axis`. |
| |
| |
| **Example**:: |
| |
| |
| // given x of shape (1,2,1) |
| x = [[[ 1.], |
| [ 2.]]] |
| |
| // broadcast x on on axis 2 |
| broadcast_axis(x, axis=2, size=3) = [[[ 1., 1., 1.], |
| [ 2., 2., 2.]]] |
| // broadcast x on on axes 0 and 2 |
| broadcast_axis(x, axis=(0,2), size=(2,3)) = [[[ 1., 1., 1.], |
| [ 2., 2., 2.]], |
| [[ 1., 1., 1.], |
| [ 2., 2., 2.]]] |
