WebSo this quantity here has the property that for example, the diagonal element or the first diagonal element is expected value of x1- mu 1 squared. Okay. So it's just the ordinary variance of the first element of the vector. The second entry, second diagonal entry of this matrix is just the expected value of X 2 minus mu 2 squared. 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.

WebFor example, the diagonal of a square (d) = a√2; where 'd' is the diagonal and 'a' is the side of the square. The diagonal of a rectangle (d) = √( l 2 + w 2), where l = length of the rectangle and w = width of the rectangle.
