Krawtchouk Polynomials

[Syedafariha Bukhari]

Dear Representative,

I am having trouble for Krawtchouk Polynomials my jupyter notebook is giving error that Krawtchouk is not defined. why it is so?

[David Joyner]

So we can better help, can you please give an example of the syntax you tried?

I'm no expert on those polynomials, nor on the jupyter notebook, but
when I followed
https://doc.sagemath.org/html/en/reference/coding/sage/coding/delsarte_bounds.html
on the command line, I got this output:

sage: codes.bounds.krawtchouk(24,2,5,x)
-4/15*(x - 1)*(x - 2)*(x - 3)*(x - 4)*x + 40/3*(x - 1)*(x - 2)*(x -
3)*x - 280*(x - 1)*(x - 2)*x + 3080*(x - 1)*x - 17710*x + 42504

Does that work for you?

Thank you for your email. Actually I got to know I was using an older version of Sage then I tried this in an online notebook, and it's working.
