The Rayleigh–Ritz method is often used in mechanical engineering for finding the approximate real resonant frequencies of multi degree of freedom systems, such as spring mass systems or flywheels on a shaft with varying cross section. It is an extension of Rayleigh's method.
In 1909 Ritz developed a direct method to find an approximate solution for boundary value problems. It converts the often insoluble differential equation into the solution of a matrix equation. It is a theoretical preparatory work for the finite element method (FEM). This method is also known as Ritz's variation principle and the Rayleigh-Ritz ...
The Rayleigh-Ritz procedures in these runs only need to solve a set of 3 × 3 projected eigenvalue problems. The global Rayleigh-Ritz procedure for all desired eigenpairs is only applied periodically at the end of a fixed number of unblocked LOBPCG iterations. Such modifications may be less robust compared to the original LOBPCG.

The Rayleigh's quotient represents a quick method to estimate the natural frequency of a multi-degree-of-freedom vibration system, in which the mass and the stiffness matrices are known.
Rayleigh-Ritz method is exactly the same as Ritz method. The preceding unsigned comments were left by User:143.107.133.29.
