Description

I'm not sure if this goes here or in the docs repo and I'm not sure if this is intentional or not. But the implementation allows one to just put in one matrix for example

mdivide_left_tri_low(A); // is valid and assumes the other vector/matrix of 0s

I think this should be documented.

Research direction

Start by locating the documentation or entry point for mdivide_left_tri_low and the other mdivide_* functions. Verify whether the one-argument form is intentional and where this documentation belongs; done means the supported behavior and its expected zero vector or matrix are documented in the appropriate repository.
