A tridiagonal matrix is a matrix that is both upper and lower Hessenberg matrix. In particular, a tridiagonal matrix is a direct sum of p 1-by-1 and q 2-by-2 matrices such that p + q/2 = n — the dimension of the tridiagonal. Although a general tridiagonal matrix is not necessarily symmetric or Hermitian, many of those that arise when solving linear algebra problems have one of these properties. Furthermore, if a real tridiagonal matrix A satisfies ak,k+1 ak+1,k > 0 for all k, so tha… WebMar 9, 2024 · Let A be an n × n tridiagonal matrix such that all its entries consisting of zeros except for those on (i) the main and subdiagonals are − 1; (ii) superdiagonals are − 2. Let u be the column vector all entries are 1 so that uuT is an n × n matrix of all 1 's. This way, your matrix becomes A + uuT. Now, apply the Matrix Determinant Lemma ... Web1 Introduction. A tridiagonal matrix has nonzero elements only on the main diagonal, the diagonal upon the main diagonal, and the diagonal below the main diagonal. This special structure appears often in scientific computing and computer graphics [1, 2].
