Does a singular matrix have an adjoint matrix? My lecturer said that there is an adjoint matrix for every matrices be it singular or invertible. But I don't see how I can derive an adjoint matrix from a singular matrix?

Best ResponseYou've already chosen the best response.0oh...so a singular square matrix is still possible to have an adjoint matrix. But will a singular rectangular matrix be able to have an adjoint matrix?
