چکیده
|
The harmonic projection method can be used to compute some eigenpaires of large matrix,and it is more suitabele for finding interior eigenpairs. however, it has been shown that theharmonic proj ection method may converge erratically and even may fail to do so. in this paper,we pre sent two new tecn iques to improve convergence. the results show that the algorithmsconverges fast and works with high accuracy.
