Hi, is there a function that calculate the natural frequency for the system if the stiffness and mass matrices is available. Thanks

Natural frequency is nothing but a Eigenvalue. Here Eigenvalue of stiffness matrix and mass matrix. Go through 'eig' function. You can also extract mode shapes for the corresponding eigenvalue. I guess you are solving natural frequencies by FEM.
