eigenvector
Hi Silvia.
Dear Silvia, is there any way to find eigenvector, modal participation factor, and modal mas matrix by Opensees?

Re: eigenvector
you can get te eigenvector using a node recorder or node response command. .. the others need to be calculated

thanks for your help, but do you have a sample code for node recorder or node response command? I'm very new in opensees and i don't know much about this command. thank you:)
