[Jama] Deadlock
Philipe Dalla Bernardina
I've found a deadlock calling the method eig() of
EigenvalueDecomposition... This is possible?

could you please be more specific about the deadlock?
Do you have some sample code to reproduce it?

I can?t run Jama on my machine, but looking at this matrix with MATLAB, I can?t see anything remarkable about it numerically.
It shouldn?t give ?eig? any trouble. Of course, we don?t have the actually matrix, we only have 14-digit decimal approximations
to the actual floating point numbers, but that should make any difference in this case. I will be very surprised if we find the
trouble is with the computation. Try some other 12-by-12 symmetric matrix.
