For invertible matrices, all of the statements of the invertible … Web19 jun. 2024 · It works because A'A is guaranteed to be square, even if A is not. But A'A is not necessarily invertible (although I have never encoutered a linear regression problem where it's not). So maybe Matlab has a way to deal with that possibility, by not using inv() when it does left matrix divide. trastero aranjuez https://aurorasangelsuk.com
