[petsc-users] SLEPc mantain eigenvalue/eigenvector ordering compatible with problem matrix

2012-07-11 Thread Alessio Cardillo
Hello to all, I am using SLEPc library to solve an eigenvalue problem using the lapack solver. the solver works fine (both eigenvalue and eigenvectors are correct) but the order in which solutions are given is different from the original one. My problem is: I need to retrieve the pair (eigenval
