[petsc-dev] Symmetry acceleration of the Jacobi-Davidson method (in SLEPc)

2015-02-13 Thread Krzysztof Gawarecki
Dear All, I'm calculating eigenvalues and eigenvectors of the matrix which has specific kind of symmetry. Due to this symmetry I obtain the eigenvalues which are doubly degenerated. So eg. eigeinvalue 'e1' has eigenvectors 'a1' and 'b1'. These eigenvectors are related to each other by the
