Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. In linear algebra, the outer product typically refers to the tensor product of two vectors. The result of applying the outer product to a pair of vectors is a matrix. The name contrasts with the inner product, which takes as input a pair of vectors and produces a scalar. The outer product of vectors can be also regarded as a special case of the Kronecker product of matrices. Some authors use the expression "outer product of tensors" as a synonym of "tensor product". The outer product is also a higher-order function in some computer programming languages such as APL and Mathematica.
