Iterative Algorithms for Solving the Partial Eigenvalue Problem for Symmetric Interval Matrixes

In this paper, we consider iterative methods for solving a partial eigenvalue problem real symmetric interval matrices. Such matrices have applications in modeling many technical problems where lot of data suffers from limited variation or uncertainty. most applied problems, when some parameter values fluctuate with known amplitude, then it can be considered that is advisable to use methods. The algorithms proposed by us are built on the basis power method and its modification, so-called
