Re: Zero Column Error in TAUCS?

Hello,

I am using TAUCS for quite awhile. I should say that while the
symmetric solver (Cholesky) is extremely fast, the nonsymmetric solver
(LU) is pretty slow. In the latter case, UMFPACK is much faster.

My code to call TAUCS and UMFPACK from C++ is at

Best wishes,
