Hello
It happens on sagenb.org
which runs Sage 5.11, for which
http://trac.sagemath.org/ticket/10346
is already closed.
Do you mean some other trac ticket?
Indeed, even on 6.2.rc1, one has this error:
sage: A = matrix(SR, [[1, 2], [2, 3]]); A
[1 2]
[2 3]
sage: A.right_eigenvectors()

TypeError: eigenvectors_left() takes no keyword arguments
AFAICS we just have to replace it by
return self.transpose().eigenvectors_left(extend)
Really?
Yes.
sage: A.transpose().eigenvectors_left(extend)

NameError Traceback (most recent call

sage:
def eigenvectors_right(self, extend=True):
So 'extend' is defined where the call happens...
-leif
While eigenvectors_right() works perfectly good, right_eigenvectors() says:
Traceback (most recent call last):

This is old error described here:
http://trac.sagemath.org/ticket/10346#comment:6
The code of function is:
return self.transpose().eigenvectors_left(extend=extend)
