Abstract: | Two eigenvalue functions are provided in the MATLAB toolbox. With these two functions, a method to solve eigenvalue problem of unsymmetrical damp system is presented according to the feature of vibrational equation of pipes conveying fluid. Since the method is proved both efficiently and quickly, a shortcut is obtained to solve such problem. |
