Rank of outer product
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. More generally, given two tensors (multidimensional arrays of numbers), their outer product is a tensor. The outer product of tensors is also referred to as … Visa mer Given two vectors of size $${\displaystyle m\times 1}$$ and $${\displaystyle n\times 1}$$ respectively Or in index notation: Denoting the dot product by If Visa mer In some programming languages, given a two-argument function f (or a binary operator), the outer product of f and two one-dimensional arrays A and B is a two-dimensional array C … Visa mer • Dyadics • Householder transformation • Norm (mathematics) • Scatter matrix Visa mer The outer product of vectors satisfies the following properties: The outer product of tensors satisfies the additional Visa mer Let V and W be two vector spaces. The outer product of $${\displaystyle \mathbf {v} \in V}$$ and $${\displaystyle \mathbf {w} \in W}$$ is … Visa mer As the outer product is closely related to the Kronecker product, some of the applications of the Kronecker product use outer products.
