How to solve generalized eigenvalue problem
Web2 days ago · For our application, we expect the spatio-angular (rather than energetic) equations will be much more burdensome to solve. Following this line of reasoning, a straightforward and seemingly economical approach is to re-compute the eigenvalue during the update step, since it can be solved as a generalized eigenvalue problem. WebA new method, called the Q Z algorithm, is presented for the solution of the matrix eigenvalue problem A x = λ B x with general square matrices A and B. Particular attention is paid to the degeneracies which result when B is singular. No inversions of B or its submatrices are used.
