Dear all,
Is convolution polynomial ring implemented in Sage?
I want to implement NTRU public key cryptosystem. Hence I need
modular inverse of a polynomial also in the ring.
With regards,
Santanu

Sorry, the Piecewise class is very clunky and old.
Is something like this helpful?
sage: x = Polynom
Can't seem to get the convolution of these two functions.
f(t) = unit_step(t) - unit_step(t-3)
g(t) = unit_step(t) - unit_step(t-1)
Matlab (argghh...) does it simply: conv(f,g). I tried the methods
in the documentation: z = f.convolution(g), but no no luck getting it
to work in sage.

Do you mean this, for example?
sage: x,t = var(
Hi,
I am trying to use sage for signal analysis and didn't find a solution
to perform symbolic convolution. Is there a way to do this?
Has anybody done something similar in sage before?
Is there a way to work with the sine integral?
I tried to get it by integrating a sinc-function but I didn't get
