I would like to know whether there is a way to monitor the evaluation of the norm of the error of FindRoot
. Sometimes the evaluation of of this for a large system can takes minutes, hours or days, and I would like to see which parameters (e.g., damping factor) can lead to improvement of the performance of FindRoot
.
e.g., Suppose I solve the complex system
FindRoot[Equations, Start];
I would like to get an update at every iteration about: 1) the iteration number 2) the norm of error of the function
UnconstrainedProblems
has a few interesting functions- $\endgroup$
