Hi Sage Support,
I tested the Sbox function S.interpolation_polynomial() on the AES S-box,
and got a polynomial that I wasn't expecting. I was expecting the AES S-box
polynomial: 0x5*(x^254) + 0x9*(x^253) + 0xf9*(x^251) + 0x25*(x^247) +
0xf4*(x^239) + (x^223) + 0xb5*(x^191) + 0x8f*(x^127) + 0x6
Hi everyone,
I have a program that requires some user inputs. I know raw_input([...])
can be used for string inputs and int(raw_input([...])) for integer inputs
but I also need a matrix input from users. Is there anyone who can help me
with this?
I thought of asking the user to input a list, f
t;

Hi everyone,
I want to count the number of non-zero entries in a matrix but I can't find
a Sage command to do this. Instead, I found a NumPy command
numpy.count_nonzero to do it.
I tested it in the online Sage Cell server: https://sagecell.sagemath.org/
The code goes like this: import n

Hi,
In the midst of my Sage installation, it paused and showed "Input archive name
or "." to quit pax". I keyed in "." and it continued to process. At the end of
the installation, it showed "build succeeded" and "Build finished".
Can I confirm that my Sage installation is complete and has succ
