Well, I don't think it's that complicated really. For whatever that's worth
:-). My best attempt is here, anyway:
The short version is, for 1d and 2d inputs it acts just like dot(). For
higher dimension inputs like (i, j, n, m) it acts like any other gufunc
(e.g., everything in np.linalg) -- it treats this as an i-by-j stack of
n-by-m matrices and is vectorized over the i, j dimensions. And 0d inputs
are an error.
