Is this what you want?
sage: 2+2

Hello, is there any way how to access the last result in Sage?
Something like % in Maxima?
Thank you.

I'm preparing an arXiv submission that will include an appendix of Sage
code along with a separate .sage file with the code. Working with Sage I
have come to assume that all code not doctested is broken, so I'd like
to include doctests. I've written up my docstrings, but when I run "sage

but only works the first time. If you save & quit your work, after
trying again it fails. This is because when saving it converts
"números" to "números".

Thanks Jason, that will certainly save myself and others some time
trying to figure out what's going on.

Okay, here's the story: I wanted to plot a Fourier transform of a
Gaussian that is truncated (mulitplied by unit step function). Using
"integral", I got an answer that looked nice, but contained an error
function with an imaginary argument. Because that error function
couldn't be evaluated, I c

For further information, you can look on the scipy documentation webpage

Sage is great software that I rave about in pretty much all of my
classes except for probability theory. I’d like to get some info on a
few topics to clear some things up so that I can use these for classes

It was so difficult to continue my research without it! And I am so
glad Sage project have real support :-)

The accent marks is a problem in Notebook. I am writing some texts in

Try this instead:

Ts=0.1
# one change here:
var('f')
z=exp(I*2*pi*Ts*f)
p=(2/Ts)*(z-1)/(z+1)
H = (p^3)/((p-Pole1)*(p-Pole2)*(p-Pole3))

I think the Type Error is coming from your use of the round function.
If I run: -
H, p, Pole1, Pole2, Pole3, Ts, z, f = var("H p Pole1 Pole2 Pole3 Ts z
f")
p = (2/Ts)*(z-1)/(z+1)
z = exp(I*2*pi*Ts*f)
r=2*2*pi
Pole1=r*exp(I*2*pi/3)
Pole2=-r
Pole3=r*exp(-I*2*pi/3)
Ts=0.1
H = lambda p: (p^3)/((p-P
This did the trick.
Thanks

I use sage for all my figures, and at the moment to get exactly what I
want I use axes=False and create my own axes and labels with text()
and line() commands. This is somewhat painful at first but after
writing a couple of functions its not too bad. Hopefully Mike and
others' enhancements will

I was trying this:
r=2*2*pi
Pole1=r*exp(I*2*pi/3)
Pole2=-r
Pole3=r*exp(-I*2*pi/3)
Ts=0.1
z = exp(I*2*pi*Ts*f)

H = (p^3)/((p-Pole1)*(p-Pole2)*(p-Pole3))

Quite a while back I submitted a
proposed replacement for tasteful_ticks:
while avoiding overhaul of the axes code,
it did produce satisfactory tick marks for a
larger parameter region than the current routine.
Has anything ever come of it?
