%EIG    Eigenvalues and eigenvectors.
%   E = EIG(X) is a vector containing the eigenvalues of a square 
%   matrix X.
%
%   [V,D] = EIG(X) produces a diagonal matrix D of eigenvalues and a
%   full matrix V whose columns are the corresponding eigenvectors so
%   that X*V = V*D.
% 
%   [V,D] = EIG(X,'nobalance') performs the computation with balancing
%   disabled, which sometimes gives more accurate results for certain
%   problems with unusual scaling.
% 
%   E = EIG(A,B) is a vector containing the generalized eigenvalues
%   of square matrices A and B.
%
%   [V,D] = EIG(A,B) produces a diagonal matrix D of generalized
%   eigenvalues and a full matrix V whose columns are the
%   corresponding eigenvectors so that A*V = B*V*D.
