The tridiagonal matrix algorithm

WebFeb 1, 2024 · A tridiagonal matrix [1], [2] is a square matrix whose entries are located only on the first diagonals above and below the main diagonal, and the main diagonal itself. Tridiagonal matrices arise naturally in many fields and have been intensely studied over the years [2], [1], [3], and even now [4], [5]. They are invertible in O ( n 2).
