I'm having trouble getting roots for this matrix. The example has to do with finding the natural frequency and mode shapes of a a simple rigid rotor system on anisotropic flexible supports. I have the formula, answer, and polynomial from the matrix equation just struggling to find the roots. Please help.
The question is example 3.6.1(a) finding roots s1-8.
I believe im solving for q and q` but im not sure how to put this in matlab. Or maybe us
