Methods and programs in C++ for eigenvalue problems

Solving the eigenvalue problems is of great importance in the dynamic analysis of mechanical systems and structures. The paper presents the computer programs in C++ and their implementation in order to determine the eigenvalues and eigenvector using Hotelling's method combined with the power method. To show the implementation method of the programs there were analyzed mechanical systems with many degrees of freedom for which the module forms of the eigenvectors were represented graphically.
