Hi all, as we all know, java does not provide any means of detecting overflows and/or underflows in numerical calculations off-the-shelf. While investigating some numerical stability problems and trying to improve the eigenvalue implementation, I was thinking about instrumenting certain operations to detect such things.
In fact there already exists something that does exactly this (and some other things like smearing, cancellation, ...) The thing is called cojac and can be found here: http://code.google.com/p/cojac/ It is a very nice tool, so in case somebody did not know about it, give it a try. Thomas
