Diagonal matrices and diagonals of a matrix
WebHere are the properties of a diagonal matrix based upon its definition.. Every diagonal matrix is a square matrix. Identity matrix, null matrix, and scalar matrix are examples of a diagonal matrix as each of them has … WebJun 28, 2024 · Summing all n full m*n matrices will recover the matrix (A' * B), but this is not cheaper than computing (A' * B), because it involves computation of all elements of (A' * B). So if SVD is involved, there is no efficient way of getting diagonal elements of (A' * B) by only computing the diagonal elements.
