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… Web4 Block matrix determinant. 5 Block diagonal matrices. 6 Block tridiagonal matrices. 7 Block Toeplitz matrices. 8 Block transpose. 9 Direct sum. 10 Application. 11 See also. 12 …
WebDec 30, 2015 · A non-sparse n x n matrix has a determinant involving n! terms of length n so unless there are entries that are 0, the memory requirements would be in excess of n * (n!) . If your matrix is not marked as sparse then all n! of those calculations might actually be done (though the position of the 0s might matter in the efficiency.)
