The method presented can be generalizable to other problems. It has been shown that the inverse of a tridiagonal matrix can be compactly represented by two sequences {ui} and {vi} [2, 3, 4, 21]. Specifically, the determinants of the n × n Toeplitz tridiagonal matrices with perturbed columns (type I, II) can be expressed by using the famous Fibonacci numbers, the inverses of Toeplitz tridiagonal matrices with perturbed columns can also be expressed by using the well-known Lucas numbers and four entries in matrix ð¸.

I have checked multiple papers on this but I have been stuck for a while. Related work. The highly accurate computation of the eigenvalues of a symmetric definite tridiagonal matrix is an important building block for the development of very efficient methods for the calculation of eigenvectors of such matrices. A well known numerical task is the inversion of large symmetric tridiagonal Toeplitz matrices, i.e., matrices whose entries equal a on the diagonal and b on the extra diagonals ($$a, b\in \mathbb R$$).The inverses of such matrices are dense and there exist well known explicit formulas by which they can be calculated in $$\mathcal O(n^2)$$.In this note we present a simplification of the â¦ Then, applications are given, showing very good accuracy. the inverse and solve linear systems of equations where symmetric tridiagonal and symmetric circulant tridiagonal nonsingular matrices appear.
