How to solve generalized eigenvalue problem

WebOct 15, 2013 · You can solve the problem mu*A*u=B*u and then find lambda=1/mu. sygvx is applicable for this problem. Of course, you'll have to find 5 biggest eigenvalues. Of course, possibility of mu to be equal to 0 should be considred separately. Victor 0 Kudos Copy link Share Reply Ever_B_ Beginner 10-19-2013 02:50 PM 314 Views 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.
