I now know that inverses are only defined for square matrices. My question is: is this because inverses for non-square matrices do not exist, i.e. there is no (m by n) matrix A for which there exists an (n by m) matrix B such that both AB = I and BA = I is true?
Or is it just done for convenience? In this cases, can we indeed find a (m by n) matrix A for which there exists an (n by m) matrix B such that both AB = I and BA = I is true?
Thanks!
