[Trilinos-Users] updating preconditioner with MueLu

In the past I've used AztecOO and ML (with smoothed aggregation) for 
solving a linear system multiple times, with the A matrix values 
changing each time.  To do this I use ML's function 
'ComputePreconditioner()' to update the preconditioner each time my A 
matrix changes.

I am now interested in using MueLu in place of ML, but I'm not sure 
how to update my preconditioner when A changes. 

Does MueLu have a function that is equivalent to ML's 
ComputePreconditioner() function?

Thank you,
