[Chris Cheng <chris.cheng@xxxxxxxxxxxx>]

i always wonder if the matrix is inverted through implicit
method such as ICCG instead of explicit LU deposition, will
the round off error still produce +ve off diagonal C elements.

Thanks to all who responded on my question of non-negative
off diagonal elements in a capacitance matrix.

As I thought, the concensus opinion was that the very small
positive number was down in the numerical noise and is essentially
a zero entry in the matrix.

Thanks again.
