• ### Definition of Outer Product Chegg

The tensor product of two coordinate vectors is termed as "Outer product". This is a special case for "Kronecker product of matrices". Let u and v be vectors. Then the outer product of u and v is w = uvT. The outer product is same as the matrix multiplication uvT also u is denoted by m 1 column vector and v is denoted by n 1 column vector.

Posts about outer product written by Krishan. The CP decomposition is sometimes expressed in the form of factor matrices where the vectors from the rank one tensor components are combined to form factor matrices. For the decomposition expression shown above the three factor matrices A B and C will be formed as shown below Often the vectors in rank one tensors are normalized to unit length.

The outer product u ⊗ v is equivalent to a matrix multiplication uv T provided that u is represented as a m 1 column vector and v as a n 1 column vector (which makes v T a row vector). 1 For instance if m = 4 and n = 3 then. For complex vectors it is customary to use the conjugate transpose of v (denoted v H) . Contrast with inner product. If m = n then one can take the matrix
