State for matrix As

[Leonawyciii]

Hi Dr. Cui and other developers,

when I get the matrix with ss.EIG.As, how do I get each state of the A matrix? Does ss.EIG.x_name show each state corresponding to the A matrix? or I can find the state in the section EIGENVALUE DATA in the file of SMIB_eig.txt.
Also, when I converge the As from andes to Matlab, how to know the state corresponding to each row of the A matrix?

Hello, the states corresponding to each row is in ss.EIG.x_name. I'm not sure about the differences in your questions.

Thank you for your answer. It is helpful. In the _eig.txt file, the EIGENVALUE DATA also shows some values with status. What is the meaning of these data?

[cuihantao]

These are the participation factor of the states (shown to the left) in the modes. The modes can be in any order, so they are referred to by numbers.

Once again, thank you for the information and for being so helpful.
