Abstract: This paper deals with the reconstruction of symmetric tridiagonal matrices and periodic symmetlic tridiagonal matrices from eigen-pairs of the matrix and its largest leading principal matrix. The necessary and sufficient conditions for the existence and uniqueness of the solution are given. Some numerical algorithms are presented.
