In linear algebra, a diagonal matrix is a matrix in which the entries outside the main diagonal are all zero; the term usually refers to square matrices. Elements of the main diagonal can either be zero or nonzero. An example of a 2×2 diagonal matrix is See more As stated above, a diagonal matrix is a matrix in which all off-diagonal entries are zero. That is, the matrix D = (di,j) with n columns and n rows is diagonal if However, the main diagonal entries are unrestricted. See more Multiplying a vector by a diagonal matrix multiplies each of the terms by the corresponding diagonal entry. Given a diagonal matrix $${\displaystyle \mathbf {D} =\operatorname {diag} (a_{1},\dots ,a_{n})}$$ and a vector This can be … See more As explained in determining coefficients of operator matrix, there is a special basis, e1, ..., en, for which the matrix $${\displaystyle \mathbf {A} }$$ takes the diagonal form. Hence, in the defining equation In other words, the See more The inverse matrix-to-vector $${\displaystyle \operatorname {diag} }$$ operator is sometimes denoted by the identically named The following property holds: See more A diagonal matrix with equal diagonal entries is a scalar matrix; that is, a scalar multiple λ of the identity matrix I. Its effect on a vector is scalar multiplication by λ. For example, a 3×3 … See more The operations of matrix addition and matrix multiplication are especially simple for diagonal matrices. Write diag(a1, ..., an) for a diagonal matrix whose diagonal entries starting in the upper left corner are a1, ..., an. Then, for addition, we have diag(a1, ..., an) + … See more • The determinant of diag(a1, ..., an) is the product a1⋯an. • The adjugate of a diagonal matrix is again diagonal. See more WebDescription. D = diag (v) returns a square diagonal matrix with vector v as the main diagonal. D = diag (v,k) places vector v on the k th diagonal. k = 0 represents the main …
