Hi, has something changed in matrix inversion code lately? I have code that is working with ROOT version 3.04.02 on linux and solaris. We try now to migrate to a more uptodate ROOT. We have tried ROOT 4.00.08 and ROOT 4.01.02 Both version give warnings: Warning in <InvertLU>: Determinant under/over-flows double: det= 0.0893 2180 and the result is garbage. I will try to dump the matrix before the call to make a simple example. But if you have already an idea in the mean time... By the way, I also need a way to disable messages and rather recuperate a status. Those messages clash with our error reporting method. Is that possible?
