[petsc-users] Question about eigenvalue and eigenvectors

[김성익]

Hello,


I tried to calculate the eigenvalues and eigenvectors in 3 by 3 matrix
(real and nonsymmetric).
I already checked the kspcomputeeigenvalues and kspcomputeritz.

However, the target matrix is just 3 by 3 matrix.
So I need another way to calculate the values and vectors.
Can anyone recommend other methods that are efficient for such small size
problems??

Thanks,
Hyung Kim
