PCLUSetUseInPlace
Tells the system to do an in-place factorization. For some implementations, for instance, dense matrices, this enables the solution of much larger problems.
Synopsis

Input Parameters
pc -the preconditioner context
Options Database Key
-pc_lu_in_place -Activates in-place factorization
Note
PCLUSetUseInplace() can only be used with the KSP method KSPPREONLY.
This is because the Krylov space methods require an application of
thematrix multiplication, which is not possible here because the matrix
hasbeen factored in-place, replacing the original matrix.
