Thank you Hong,
I already looked at those examples after not achieving the successful
results I decide to share it. It seems that I don't know how to read?
values from the vectors, EPSGetEigenvector(eps,1,vec,PETSC_NULL); retrieves
no errors which I assume that it returns the eigenvectors to corresponding?
eigenvalue(which is second in my case).
I use following notation to read values from vectors, ?here I'm not sure?
whether the "&vec[i] or vec[i]" ?can be used to read the values from vector.?
Vec vec;
for (i=0;i<9;i++)
? {
? ? PetscPrintf(MPI_COMM_WORLD," %3.8f: ",&vec[i] );
? }
Regards,
