WebThe identity matrix is a matrix, but the Kronecker delta technically is not. $ \delta_{ij} $ is a single scalar value that is either 1 or 0 depending on the values of $i$ and $j$. This is also why tensor notation is not in bold, because it always refers to individual components of tensors, but never to a tensor as a whole.

WebSuﬃx notation can also be used with matrices. For a matrix A, we write a ij to denote the entry in the ith row and jth column of A (for each i = 1,2,3 and j = 1,2,3). We write either A = (a ij) or [A] ij = a ij – these equations are equivalent – to indicate this. (Sometimes the upper-case letter is used instead, in which case the matrix A ...
