[petsc-users] KSPBuildResidual in ex42.c

[Klaij, Christiaan]

In src/ksp/ksp/examples/tutorials/ex42.c.html the Stokes system
is solved and KSPBuildResidual is used to compute the residuals
for the velocity components and pressure individually. Are these
the preconditioned residuals or the true residuals? And how to
get both?
