'''about expression of eigenvalue decomposition: ''' when we write A=VDV', the D, eigenvalues, could be explained as a scalar; however, it actually is a set of numbers that forms a diagonal matrix. As AV=VD, and VD is not DV, writing the equation as AV=DV is simply wrong, isn't it? Csa slb (talk) 05:17, 23 January 2015 (UTC)
