WebJun 19, 2024 · @Jamie Al, Matlab's left divide may not use the equation I gave above - @John D'Errico says it doesn't, and I trust him. The equation I gave in my comment (not my original answer) is standard in a statistics class when discussing linear regression. It works because A'A is guaranteed to be square, even if A is not. guitar lesson white ladder
