By default, this function checks the error of all singular triplets and prints
the singular values if all of them are below the requested tolerance.
If the viewer has format=<A HREF="https://petsc.org/release/manualpages/Viewer/PetscViewerFormat.html#PetscViewerFormat">PETSC_VIEWER_ASCII_INFO_DETAIL</A> then a table with
singular values and corresponding errors is printed.
