I'm sure my request isn't unique: one of the major goals of Sage is to
provide a platform that allows people to _verify_ it, which is par for
the course for any mathematician. I'd lik

This is a known bug. http://trac.sagemath.org/sage_trac/ticket/9314

Hi. When using Sage notebook in typesetting mode, a leading minus

Hi,
I got a first result, but it only works when I "type" it in the command
line interface.

Hi,
I played with the dirac_delta function but didn't get the results that I
need.
In the end, I need to be able to plot and calculate functions that are
multiplied with a dirac comb like

But I didn't find out how to do
Can't you regard the coefficients as a LFSR and then use the
connection polynomial? I'm not saying that there is no work
to be done, but I think the hardest part, the Berlekamp-Massey algorithm,
is implemented.
