    Fix Version/s:     (was: 2.2)
                   2.1

This issue should really be fixed for 2.1

> eigenvectors computation is wrong when several vectors share the same 
> eigenvalue

> A typical example is to decompose identity matrix. There is only one 
> eigenvalue: 1.0. Instead of returning n different eigenvectors forming a 
> complete vector base, the same vector is returned n times.
