j**********t 发帖数: 12	1 Suppose A is a real and symmetric nxn matrix, what is the complexity to find V and D such that A = VDV', is it n^3 or n^2? Thanks
h**********k 发帖数: 168	2 n^3 in matlab. can be worse in some other implementations.
d*****l 发帖数: 8441	3 If the matrix is special, it might be possible to reduce it, I guess.
