## Abstract Helmholtz equations with variable coefficients are known to be hard to solve both analytically and numerically. In this paper, we introduce a numerical multigrid solver for one‐dimensional Helmholtz eigenvalue problems with periodic potentials and solutions. The solvers employ wave–ray

The shooting method is a numerically effective approach to solving certain eigenvalue problems, such as that arising from the Schrodinger equation for the ẗwo-dimensional hydrogen atom with logarithmic potential function. However, no complete proof of its rationale and correctness has been given unt
Matlab is a high-level computing environment that is rapidly gaining popularity for the execution of matrix computations. This paper discusses a major inconvenience that may arise if Matlab is used for the numerical solution of generalized eigenvalue problems. Matlab normalizes the eigenvectors to u
In this paper a novel iterative method of multilevel type for solving large-scale generalized eigenvalue problems encountered in structural dynamics is presented. A preconditioned iterative technique, which can be viewed as a modification of the Subspace Iteration method, is used for simultaneous ca
