Determinant Eigenvalue and Inverse Matrix of a Tridiagonal Matrix

삼대각선행열의 행열식 고유값 및 역행열

A large set of linear equations which arise in many applications, such as in digital signal processing, image filtering, estimation theory, numerical analysis, etc. involve the problem of a tridiagonal matrix. In this paper, the determinant, eigenvalue and inverse matrix of a tridiagoanl matrix are analytically evaluated.
