% Add to global matrices K_global(element_dofs, element_dofs) = K_global(element_dofs, element_dofs) + k_e; M_global(element_dofs, element_dofs) = M_global(element_dofs, element_dofs) + m_e;

For a cantilever, the characteristic equation is: Dynamic Analysis Cantilever Beam Matlab Code

However, the code is not without limitations. A simple Euler-Bernoulli beam model neglects shear deformation and rotary inertia, making it inaccurate for short, deep beams. Furthermore, the number of elements must be chosen carefully—too few yields inaccurate higher modes, while too many increases computational cost unnecessarily. A well-documented code will include convergence studies to validate the mesh. % Add to global matrices K_global(element_dofs
