Determining Frequencies of Free Longitudinal Vibrations of Rods by Analytical and Numerical Methodsgebraic equations. The required oscillation frequencies are defined as the eigenvalues of a square matrix. At the final stage of determining the frequencies of free oscillations, a numerical-graphical method is used, implemented in the environment of the Matlab computing complex. A concrete example of the solution is given. Conclusions are drawn.
