I suceed to install lapack library and I ran a modal analysis on a beam to 
determine modal frequencies. So I used eigenanalysis with MBDyn. I was 
expected into the m file for each modes a frequency with a vector. But 
when I open this file, there is alpha (with real, imaginary and beta 
component), right eigenvectors and left eigenvectors, I am not used to 
these name.
I don't have matlab neither octave yet, but is it possible to extract 
modal frequencies by reading the m file?

Best regards,
Romuald Noret
