[petsc-users] Eigensolution of Dirichlet Constrained problems

   When solving an eigenproblem with Dirichlet constraints on some of the DoFs, I have so far been creating a new matrix including only the unconstrained rows/columns and the calling the eigensolver on that. This works without issues. 

    I am writing to check if there are other recommended ways to handle such constraints in SLEPc.
