[Trilinos-Users] run time changing matrix

I need to use in my code an Epetra_FECrsMatrix that changes during the 
execution of the code. In particular the pattern of the matrix may vary 
at different time steps, increasing or decreasing the number of non-zero 
elements. In general this number is quite small.

Could you please suggest me the most efficient way (in terms of memory 
usage and CPU time to solve the linear system) to implement this feature?

Thank you,
