Subroutine Package for the Efficient Solution of the Eigenproblem of Real Symmetric Toeplitz Matrices.

摘要

We discuss a subroutine package for solving the eigenproblem of bisymmetric Toeplitz matrices. When the eigenvalues and eigenvectors of a bisymmetric Toeplitz matrix are computed, storage requirements and execution time are reduced by taking advantage of the special structure of the matrix.
