In principle you are right, but even though I use masked arrays
in this operation, when the operation itself is done no masked
values remain. Thus, my code works very well with the "old"
Numeric--and has worked well for some time. That said, I will
try your suggestion of doing a "filled" on the matrix before
sending it off to the inverse module.
Thanks,
Daran
