### 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=uv T. The outer product is same as the matrix multiplication uv T also u is denoted by m 1 column vector and v is denoted by n 1 column vector. Let be two vectors.
