Matrix Multiplication - The Inner and Outer Products

WebIn 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 their tensor product, and can be used to … WebMore explicitly, The outer product. is a row vector multiplied on the left by a column vector: where.
