Web3 sep. 2013 · It should be observed that A = X T X implies A symmetric: A T = ( X T X) T = X T X T T = X T X = A; thus a positive semi-definite A would automatically be symmetric if the assertion A = X T X were true. To see that A positive semi-definite is not sufficient to force A = X T X, consider the 2 × 2 matrix (6) A = [ λ ϵ 0 λ], and let v = ( x, y) T. Webcompute [ x 1, x 2] A [ y 1 y 2] T for a 2 x 2 symmetric matrix A = [ [ a, b], [ b, c]] . you get a x 1 y 1 + b ( x 1 y 2 + x 2 y 1) + c x 2 y 2. this expression is clearly symmetric in x and y i.e., does not change when x and y are exchanged. for an n x n matrix you may want to use sigma notation.
