Determinant of a tridiagonal matrix
WebA band matrix with k 1 = k 2 = 0 is a diagonal matrix; A band matrix with k 1 = k 2 = 1 is a tridiagonal matrix; For k 1 = k 2 = 2 one has a pentadiagonal matrix and so on. Triangular matrices. For k 1 = 0, k 2 = n−1, one obtains the definition of an upper triangular matrix; similarly, for k 1 = n−1, k 2 = 0 one obtains a lower triangular ... Web1 1 Introduction The determinant is one of the basic parameters in matrix theory. The determinant of a square matrix A = (ai,j ) ∈ Cn×n is defined as X n Y det(A) = sgn(σ) ai,σ(i) , σ∈Sn i=1 where the symbol Sn denotes the group of permutations of sets with n elements and the symbol sgn(σ) denotes the signature of σ ∈ Sn .

Webthat the trace of the matrix is the sum of the eigenvalues. For example, the matrix " 6 7 2 11 # has the eigenvalue 13 and because the sum of the eigenvalues is 18 a second eigenvalue 5. A matrix with nonnegative entries for which the sum of the columns entries add up to 1 is called a Markov matrix. Markov Matrices have an eigenvalue 1. Proof.

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.
