THE problem of calculating the eigenvalue using the output impedance matrix from feko

Altair Forum User

So many values of the output impedance matrix from feko is too small, i can't use the eig function from matlab to calculate the eigenvalue,I don't konw how to deal with .

Could you give me some efficient method ?I would appreciate it very much！

Hi, The data you are extracted is wrong. I made the same mistake. The order of the matrix elements are much more lower than this. You can use Doruk Tayli's python code https://github.com/dtayli/fekomat or matlab codes https://github.com/cemagg/SUN-EM to extract the .mat file data . Good luck
