Hi people,

I know this is not the place to post this, but maybe someone can point me to the right place. I am using UMFPACK in a FEM code, without using Eigen. I am running some test against GSL and the answer to the Ax=b problem is different. I am thinking maybe a rounding up error may be involved, but so far I have not been able to figure it out. Any ideas on where to ask or who to contact?

Thanks,
