[petsc-users] About left eigenvector for general eigenvalue problem

[yuqing xia]

Hello everyone

I am trying to solve a general eigenvalue problem.
A x=\lambda B x
I also need to get the left eigenvector
y A=\lambda y B

I tested the result  for a special case where A and B are real and
symmetric. The left and right eigenvector should be the same. However,
there are not.
Then I tried to solve the problem
A x =\lambda x
The left and right eigenvectors are the same in such case. So I am
wondering what is the reason. Thanks.
