Evan Lezar is still having a problem:
Hi

I think Anders is correct. I have just had a look at the SystemAssembler
code, and it does seem to also place ones on the diagonals of the matrix
to which the boundary conditions are being applied. In addition, I am
not solving a linear system, but eigenvalue problems and as such b is a
Matrix not a Vector.

At present I am manually removing the rows and columns for the matrices
that correspond to (zero) Dirichlet conditions and then reconstructing
the correct solution vector from the eigenvector that I obtain. This is
fine for testing and getting the rest of the system running.

Thanks for the help so far.

Evan
