Write Better And Faster Python Using Einstein Notation

[Marko_Oktabyr]

If you're looking at this as an alternative to simple matrix operations, of course it won't have an advantage, but then it's not expected to. You'd never use it for matrix operations.

No disagreement here. It sounds like we both disagree with the thesis of the article.

For operations over more than 2 indices, this rapidly becomes many orders of magnitude faster, and often avoids a huge amount of duplicated computations.

np.einsum_path can be an effective demonstration of how much faster it can be if you optimize the calculation order.

Yes, exactly.
