WebApr 17, 2024 · The Rayleigh-Ritz method is an approximation scheme and you can choose the number of terms in the basis set. So you could, for example, Find a cubic that has work and energy balanced, and has some boundary conditions satisfied - x0 = 0, X1 = 0, and 1 more of your choosing, maybe equal slope at the endpoints. 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.
