As far as I know, there is no "eigenvector" of a matrix, but a set of 
eigenvectors. To represent that set, you pic one vector out of this set - 
normally one of the normalized vectors inthat set.
You get the "unnormalized" ones by multiplying your eigenvectors by a real 
number. If you are looking for a certain unnormalized eigenvector, you might 
be thinking of a certain problem or algorithm. Without knowing that 
algorithm, it will be hard to tell you by which number you have to multiply 
the results delivered by gsl.
