Rank of outer product

WebbThe outer product of the vectors x and y is xyT. Note that x and y do not have to be of the same length, and that the outer product is a matrix. In particular, it is a matrix of rank one as each column is linearly dependent on x. Let X be an m by k matrix, and Y a k by n matrix. The outer product expansion of two matrices X and Y is ∑ Webbidentity by a rank-1 matrix (the columns of the outer product uuT are all parallel to u). The product of a matrix with H is called a \rank-1 update" and is e cient to compute. (Note that a Gauss transformation can be written in the same way: G= I T˝e k . It is also a rank-1 update, but also has a sparse structure.) QR factorization algorithm.

Webb22 mars 2024 · We construct a rank-1 matrix A i ∈ R m x n as: A i := u i v i T, which is formed by the outer product of the ith orthogonal column vector of U and V. Each A i is then multiplied by its corresponding σ i in Σ, and all the rank-1 matrices are summed up to the chosen rank approximation.

In linear algebra, the outer product of two coordinate vectors is a matrix. If the two vectors have dimensions n and m, then their outer product is an n × m matrix.
