Re: [eigen] BiCGSTAB iteration count

[ Thread Index | Date Index | More Archives ]

solver.iterations() == 0 means that the initial guess was good enough, and so no iteration occurred at all.

I am using Eigen 3.2.4. Sometimes, the BiCGSTAB solver gives me solver.iterations() == 0 even when == Eigen::Success.

Is this because iterations() returns the number of iterations minus one?

If this is unexpected behaviour, I can create a minimal example for the mailing list.
