modal analysis on a rotor system to determine the natural torsional frequencies and mode shapes of the system

This code performs modal analysis on a rotor system to determine the natural torsional frequencies and mode shapes of the system. The rotor system consists of multiple parts connected by torsional stiffness elements. The code calculates the torsional stiffness matrix (K) and torsional mass matrix (M) based on user-defined input for the number of rotor parts, their masses, and the stiffness between them. The eigenvalue problem is then solved to obtain the eigenvalues (L) and eigenvectors (V) of the system. From the eigenvalues, the natural frequencies (Freqs) of torsional oscillations are computed.
