Justin,
Sorry TAO simply doesn't even collect this information currently. But yes
we should definitely make it available!
Jason,
Could you please add this; almost all the TaoSolve_xxx() have a local
variable iter; change that to tao->niter (I'm guess this is suppose to capture
this information) and add a TaoGetIterationNumber() and the uses can access
this. Also modify at the end of TaoSolve() -tao_converged_reason to also print
the iteration count. At the same time since you add this you can add a
tao->totalits which would accumulate all iterations over all the solves for
that Tao object and the routine TaoGetTotalIterations() to access this. Note
that TaoSolve() would initialize tao->niter = 0 at the top.
Thanks
Barry
