hi all,
now free solver interalg (http://openopt.org/interalg , based on
interval analysis) can solve ODE dy/dt = f(t) with guaranteed
specifiable accuracy.
For more details see http://openopt.org/ODE , there is an example of
comparison with scipy.integrate.odeint, where latter fails to solve a

Hi everybody,
I am implement Patterson Algorithm for Goppa code,
I am copying lines from paper How SAGE helps to implement Goppa
Codes and McEliece PKCSs [attach], and my test is a random vector .
the error are in Line 77,
I expect get roots from \sigma (locator polynomial), but
implementation
I don't think you should need to call _add_, but this looks like a bug to me:

Hello,
I'm trying to simplify the list [pi/4..3*pi], which gives [(1/4)*pi, (1/4)*pi +
1, (1/4)*pi + 2, …] so that I get [pi/4, 5*pi/4, 9*pi/4, …]. Is there an easy
way to do this?
Thanks much,
Gary

Those lists aren't the same. (1/4)*pi + 1 is equal to (pi+4)/4, not
5*pi/4. So I sure hope there's no way to simplify your first list into
your second one. If I add in one more term at beginning so that Sage can
tell what the difference is between consecutive terms, I get something
perhaps

Suppose I have two ideals I J in k[X_1,\cdots,x_n], where k is a
field. How do I reduce an ideal I wrt ideal J.
e.g. Singular provides me a command
singular reduce(I,std(J));
Without moving back and forth to Singular, is it possible to implement
this in sage?
I tried the following code:
