Jordan canonical form — an 'almost' diagonalised matrix, where the only non-zero elements appear on the lead and super-diagonals.Linear independence — two or more vectors are linearly independent if ...
Cabibbo-Kobayashi-Maskawa matrix — a unitary matrix used in particle physics to describe the strength of flavour-changing weak decays.Density matrix — a matrix describing the statistical state of a ...
The following matrices find their main application in graph and network theory.Adjacency matrix — a square matrix representing a graph, with aij non-zero if vertex i and vertex j are adjacent.Biadjac ...
The following matrices find their main application in statistics and probability theory.Bernoulli matrix — a square matrix with entries +1, ?1, with equal probability of each.Centering matrix — a m ...
This matrix product is denoted AB. Unlike the product of numbers, matrix products are not commutative, that is to say AB need not be equal to BA. A number of notions are concerned with the failure of ...
The list below comprises matrices whose elements are constant for any given dimension (size) of matrix. The matrix entries will be denoted aij. The table below uses the Kronecker delta δij for two in ...
The following lists matrices whose entries are subject to certain conditions. Many of them apply to square matrices only, that is matrices with the same number of columns and rows. The main diagonal o ...
This page lists some important classes of matrices used in mathematics, science and engineering. A matrix (plural matrices, or less commonly matrixes) is a rectangular array of numbers called entries. ...
