Hello,
i have built a code for determining the eigenvalues for a vibration problem and plotted them. But there is something that i couldn't understand. There is no a value for eigenvalue-1 for s specific beta interval. What happens there? are roots complex or sth else?
thanks for your help.
are roots complex or sth else?
Yes, as you can see by inspecting the appropriate vectors:
Now that you know which values for k fail/produce non-real results, you may investigate in detail what happens if you think that that should no be that way.
