WebApr 1, 2024 · I want to use the ML vector to create a diagonal matrix of only the values of the ML vector on the diagonal and make a new ML matrix with zeros everywhere else and the values of the ML vector along the diagonal of the new ML matrix. Essentially I am trying to write the code for diag(ML). 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.
