I'm doing tutorials in Matlab for school, testing what should and shouldn't work. So when I tried subtrating a 1xn matrix from an mx1 matrix and vice versa, it resulted in an nxn matrix in both cases when it should have resulted in:
"??? Error using ==> -
Matrix dimensions must agree."
according to the tutorial.

Sounds like the tutorial is for an older version of MATLAB, and the behavior changed since then. Here is an article related to that change.
