It is possible to set the machine in such a way that it will produce kl-C instead of C. This is useful in finding the inverse AT of a matrix A by a process of successive approximations such as XB+1 = Xn(2I-AXn).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
