![QR decomposition - Wikipedia, the free encyclopedia]()
en.wikipedia.orgIn linear algebra, a QR decomposition (also called a QR factorization) of a matrix is a decomposition of a matrix A into a product A = QR of an orthogonal matrix Q and an upper triangular matrix R. QR decomposition is often used to solve the linear least瀏覽：988 -
![QR-Decomposition for a 2x2 Matrix - YouTube]()
www.youtube.comLinear Algebra: We give a general formula for a QR-decomposition of a real 2x2 matrix; that is, we show how to decompose any 2x2 matrix A as a product QR where Q is orthogonal and R is upper triangular. We also note one set of conditions under which the f瀏覽：701

The practical QR algorithm [edit] Formally, let A be a real matrix of which we want to compute the eigenvalues, and let A 0:=A. At the k-th step (starting with k = 0), we compute the QR decomposition A k =Q k R k where Q k is an orthogonal matrix (i.e., Q...

The orthogonal decomposition of a vector y in R^n is the sum of a vector in a subspace W of R^n and a vector in the orthogonal complement W^_|_ to W. The orthogonal decomposition theorem states that if W is a subspace of R^n, then each vector y in R^n can...
