Yeah, you should simply skip the LU step and solve the vector with the old LU, if the vector has changed. You should also emit debugging information because it means that there is probably something wrong with one of the components. Nb, there are some pathalogical circuits that inherently produce invalid matrices. I can send you an example. -- New president: Here we go again... Chemistry.com: A total rip-off.
