The outer product contrasts with: The dot product (a special case of "inner product"), which takes a pair of coordinate vectors as input and produces a... The Kronecker product, which takes a pair of matrices as input and produces a block matrix Standard matrix multiplication Visa mer 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 … 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 the element $${\displaystyle \mathbf {v} \otimes \mathbf {w} \in V\otimes W}$$. If V is an Visa mer As the outer product is closely related to the Kronecker product, some of the applications of the Kronecker product use outer products. These applications are found in quantum … Visa mer Given two vectors of size $${\displaystyle m\times 1}$$ and $${\displaystyle n\times 1}$$ respectively Or in index notation: Denoting the Visa mer The outer product of vectors satisfies the following properties: The outer product of tensors satisfies the additional associativity property: Rank of an outer … 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 such that C[i, j] = f(A[i], B[j]). This is syntactically represented in various ways: in Visa mer • Dyadics • Householder transformation • Norm (mathematics) • Scatter matrix • Ricci calculus Visa mer
