Dear all, After some projection operations, I am ending up with a dense generalized non-symmetric eigenvalue problem, such as
A\phi = \lambda B\phi where A and B are given as [A11 A12] [ 0 A22] [B11 0 ] [B21 B22] So there are two large 0 blocks in A and B. Moreover, B21 = -A12^T, I was wondering if I can tailor some efficient solver for these matrices with large zero blocks? Any ideas and pointers are appreciated highly. Best regards, Umut
