Eigenvalue of tensor product of matrices
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 … WebJan 31, 2015 · But, instead, your assignment asked you to simply mechanically evaluate the tensor product of two different matrices, to see if you understand the rules @jabirali correctly applied to get the correct answer you were meant to find. So, your equation (3) is magnificently wrong: you evaluated $\boldsymbol{\sigma_2} \otimes 1\!\!1 +1\!\!1\otimes ...
