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. == Band matrix == === Bandwidth === Formally, consider an n×n matrix A=(ai,j ).
