Abstract: A new method of calculating eigenvectors and eigenvalues is discussed and applied to the vibration system. A lot of examples have proved that the method has some peculiar features, such as high accuracy and little CPU time. To set a new type resident function and then use a new type iterative formula are the two key steps of this method. The method can be easily applied to many different fields to calculate system eigenvectors and eigenvalues.
