SpletThe trace of a matrix A, designated by tr ( A ), is the sum of the elements on the main diagonal. Example 1 Find the tr ( A) if Solution tr ( A) = 3 + 4 + (−5) = 2. Property 1 The sum of the eigenvalues of a matrix equals the trace of the matrix. Proof. See Problem 20. SpletIf the matrix is not only symmetric (hermitic) but also positive semi-definite, then its eigenvalues are real and non-negative. Hence, given the properties t r ( M) = ∑ λ i and d e t ( M) = ∏ λ i, and recalling the AM GM inequality, we get the following (probably not very useful) inequality: t r ( M) n ≥ d e t ( M) 1 / n SpletTrace of a scalar.

In linear algebra, the trace of a square matrix A, denoted tr(A), is defined to be the sum of elements on the main diagonal (from the upper left to the lower right) of A. The trace is only defined for a square matrix (n × n). It can be proved that the trace of a matrix is the sum of its (complex) eigenvalues (counted with … Prikaži več The trace of an n × n square matrix A is defined as Expressions like tr(exp(A)), where A is a square matrix, occur so often in some fields (e.g. multivariate statistical theory), that a shorthand … Prikaži več If A is a linear operator represented by a square matrix with real or complex entries and if λ1, ..., λn are the eigenvalues of A (listed according to their algebraic multiplicities), then This follows from the fact that A is always similar to … Prikaži več Stochastic estimator The trace can be estimated unbiasedly by "Hutchinson's trick": Given any matrix Usually, the … Prikaži več Let A be a matrix, with Then Prikaži več Basic properties The trace is a linear mapping. That is, A matrix and its transpose have the same trace: This follows immediately from the fact that transposing a square matrix does not affect elements … Prikaži več In general, given some linear map f : V → V (where V is a finite-dimensional vector space), we can define the trace of this map by considering the trace of a matrix representation of f, that is, choosing a basis for V and describing f as a matrix relative to this basis, and … Prikaži več If a 2 x 2 real matrix has zero trace, its square is a diagonal matrix.
