thinking of it wrong. Conventional dependency tuples are (indep, dependent). Vert/horizont is a weak convention

Row/Column notation makes more sense when viewing a matrix as a linear transform on a vector space

Basically, a matrix acts on a vector. Usually from the left, as in Ax=y. The rows of A, acting on x, give elements of y.

you could act on the right, like x^T A = y, but this is clunky af. (Vectors by convention are column vectors)
