A band matrix with k1 = k2 = 0 is a diagonal matrixA band matrix with k1 = k2 = 1 is a tridiagonal matrixFor k1 = k2 = 2 one has a pentadiagonal matrix and so on.Triangular matrices Upper and lower Hessenberg matricesToeplitz matrices when bandwidth is limited.Block diagonal matricesShift matrices and … 더 보기 In mathematics, particularly matrix theory, a band matrix or banded matrix is a sparse matrix whose non-zero entries are confined to a diagonal band, comprising the main diagonal and zero or more diagonals on either side. 더 보기 In numerical analysis, matrices from finite element or finite difference problems are often banded. Such matrices can be viewed as descriptions of the coupling between the problem … 더 보기 From a computational point of view, working with band matrices is always preferential to working with similarly dimensioned 더 보기 Bandwidth Formally, consider an n×n matrix A=(ai,j ). If all matrix elements are zero outside a diagonally bordered band whose range is determined by constants k1 and k2: then the quantities k1 and k2 are called the lower bandwidth … 더 보기 Band matrices are usually stored by storing the diagonals in the band; the rest is implicitly zero.
