Is there an easy way to obtain the intermediate solution vectors given by lsqr ?
Thanks

I'm curious -- why are you interested in the intermediary steps?

Well, I'm comparing different solvers. I want to see the actual differences in the steps. I have changed the afun function that computes the inner product but the intermediate steps really don't seem to correspond. Would you agree ?
