Hello!

I am trying to calculate the eigenvector of a tensor having components strain\_xx, strain\_xy, strain\_yx and strain\_yy using the python calculator. I have given the following expression, but did not work.  
eigenvector([[strain\_xx, strain\_yx],[strain\_xy, strain\_yy]])

I am very new in Paraview. Can you please let me know how should I proceed?

Best regards  
Poulami
