Dear Sir,
Friend of mine written up following code to generate The Rudin Shapiro Sequence.
def count_11(st):
count = 0
for i in range(len(st)-1):
if st[i] == '1' and st[i+1] == '1':
count += 1
return count
def rudin_shapiro(n):
return (1-(-1)**count_11(Integer(n).str(2)))/2
The thing is every time I wanna use it, I have to run this code. Now,
I just wanna know how do I make it work like the in-built command in
sage. Like for factoring number 10. I just need to say factor(10).
Thank you very much.
Bhavin.
