[petsc-users] SetOptionsPrefix

[Dharmendar Reddy]

Hello,
         I was wondering how the <SENS,KSP,PC>SetOptionsPrefix work ?. I
can figure out from the code that SNES set options prefix sets the options
prefix to the ksp and pc objects on snes. Does it also apply the prefix to
the Matrix and vectors passed to snes as jacobian, function and solution?
or, are they considered as a independent objects ? Do i need to set options
prefix to matrix and vector objects pased to snesset jacobian and snesset
function.

Thanks
