Something like np.outer

[tolios]

Hey there, I was wondering if there exists a feature, or a way to implement a simple outer operation like the one offered by numpy: https://numpy.org/doc/stable/reference/generated/numpy.outer.html. It might be straightforward already, but if not I would find it nice to have it as a feature. Like: einouter(a, b, "i, j -> i j").

Sorry again if this is already possible, i just found out this library.

yes, that's possible:

einops.einsum(a, b, 'i, j -> i j')
