I'd really like to use einsum more often, because it allows me to code my expressions the same way I derive them on pen and paper. Unfortunately, as mentioned in the article, it's slow, because it converts your formula to a for loop.
So usually, I rewrite my formulas into messy combinations of broadcasts, transposes and array multiplications. Is there a package or an algorithm that does this conversion automatically? It seems to be a pretty straightforward problem, at least for most expressions I use.
