This program uses the Stodola method for finding the eigen values and eigen vectors of a dynamic system. Before executing the program, you have to enter in MatK the stiffness matrix, and in MatM the mass matrix.

With the execution of the program you will be asked about the number of repetitions for calculating each eigen value. The program shows even the intermediate calculations for each step. In the finish of the execution, matrix MatW contains the eigen values and the coresponding frequencies and matrix MatF contains the eigen vectors.
