matrix inversion

[Randall Mackie]

I have a collegue who is considering to use PETSc for programming
his problem. He would like to know if you can get the actual
inverse of a matrix, because this inverse is embedded in another
larger system that is then solved.

I suppose that if you solve the system directly, say with SuperLU
or MUMPS, you could get the actual inverse? I looked briefly through
the manual and documentation, but it didn't jump out at me.

Any advice here?

Thanks, Randy
