Yes, it doesn't know French. Get rid of the e with the accent over it

Hello,
the following code takes more than one minute to acheive its job.
Is there some technical problem with the server ?

Simple code =
def pgcdBoucle(a, b):
n = 0
if b > a:
a, b = b, a
while(b != 0):
a, b = b, a%b
n += 1
return (
Hi,
I need to performe a (numerical) cholesky factorization of a sparse
matrix (20x20) but I'm getting a error.
I look at this thread
https://groups.google.com/forum/?fromgroups=#!searchin/sage-devel/cholesky/sage-devel/AW4pmKx49H4/7iuet3rWYQgJ

Ahahaahah. Well, implement the Matrix version and I will implement the
graph thing. We could be checking the results ins

May be you are right. Powers of the matrix appear easier to implement
IMHO.
