Real and ordered eigenstructure decomposition.
Syntax
[xr,d] = reig(a)
[xr,d] = reig(a,Opt)
Description
Reig produces a "real" and "ordered" eigenstructure decomposition such that 
where Xr is a set of "real" eigenvectors that span the same eigenspace as the complex ones. D is a real block diagonal matrix with real eigenvalue appearing as 1 x 1 block and/or complex eigenvalue a + jb appearing as a 2 x 2 block 
Two types of ordering are available
Algorithm
The kth real eigenvector pair xr(:, k:k+1) is
