Magnitude of diagonal matrix

Webof the matrix V cannot be selected to be mutually orthogonal, and therefore the matrix VV> cannot, in general, be diagonal. Thus, the question is how to select the vectors vk such that the matrix VV> is the closest possible to being diagonal. In terms of the rows of the matrix V we would like to minimize Erms = v u u t 1 n(n−1) Xn j=1 Xn j06 ... Web[V,D] = eig (A,B) returns diagonal matrix D of generalized eigenvalues and full matrix V whose columns are the corresponding right eigenvectors, so that A*V = B*V*D. [V,D,W] = eig (A,B) also returns full matrix W whose columns are the corresponding left eigenvectors, so that W'*A = D*W'*B.
