WebThe Rayleigh-Ritz Method The nite-di erence method for boundary value problems, unlike the Shooting Method, is more exibile in that it can be generalized to boundary value problems in higher space dimensions. However, even then, it is best suited for problems in which the domain is relatively simple, such as a rectangular domain.
