Band matrix — In mathematics, particularly matrix theory, a band 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. Contents 1 Matrix bandwidth 2… … Wikipedia
Skyline matrix — A skyline matrix, or a variable band matrix, is a form of a sparse matrix storage format for a square, banded (and typically symmetric) matrix that reduces the storage requirement of a matrix more than banded storage. In banded storage, all… … Wikipedia
Packed storage matrix — Packed storage matrix, also known as packed matrix, is a term used in programming for representing an m imes n matrix. It is a more compact way than an m by n rectangular array by exploiting a special structure of the matrix.Typical examples of… … Wikipedia
Diagonal matrix — In linear algebra, a diagonal matrix is a matrix (usually a square matrix) in which the entries outside the main diagonal (↘) are all zero. The diagonal entries themselves may or may not be zero. Thus, the matrix D = (di,j) with n columns and n… … Wikipedia
