Rayleigh ritz
The Ritz method is a direct method to find an approximate solution for boundary value problems. The method is named after Walther Ritz, and is also commonly called the Rayleigh–Ritz method and the Ritz-Galerkin method. In quantum mechanics, a system of particles can be described in terms of an "energy functional" or Hamiltonian, which will measure the energy of any proposed configuration of said particles. It … WebI understand that you are getting wrong solutions but there is nothing wrong with the working of the code. I suggest you re-check your initial assumption of Y3(X) as a polynomial (try taking a combination of trigonometric functions and later use Taylor series expansion to expand them) or maybe try using different boundary conditions.

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.
