Hi,
since ask.sagemath.org seems not to work at the moment and I really need
a solution for this, I write to the mailing-list.
I need to create a zoomed subarea in a Matplotlib-Plot under sage.
In the Matplotlib galery is pretty much what i need.

Hi,
I am trying to generate pink noise with sage but I didn't have much
success - is there anybody simulating pink noise with sage?
As far as I know, there is no such function yet - would be great if you
could give me some hint.
Thanks,
Tobias

Hi,
Thanks for your reply!
Renaming doesn't work, but what I found out is, that, in my case, it
works with the following syntax:
sum(function for n_ in np.arange(-11,11,1))
Nevertheless, I'd be interested if there are other people out there
working with Signal Theory and stochastic signal descrip
x27;int' object has no attribute '_maxima_'
How can I cast these integers to numbers or what is my mistake?
Is there a better way to do this?
Thanks,
Tobi

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

Hi Amelia,
How did you try to load the file?
I guess you are using the notebook.
There it is possible to load a file with
load('').
If you are using the command line version you can also use
run
or
run -i
for running your script in the actual namespace.
Cheers..

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
Hi,
My problem is already solved.
I had to install the 'libxext-dev' package on my ubuntu for some reason.

When I use substitute_function to declare a function within an existing
equation, I get the following message:
DeprecationWarning: Substitution using function-call syntax and unnamed
arguments is deprecated and will be removed from a future release of
Sage; you can use named arguments instead, lik
Hi,
I think you are getting trouble because you are mixing two namespaces.
If you separate both packages,
for example like this:
import sympy as sp
import scipy as sc
you can choose which namespace you want to pick a function from by
saying:
f=sp.Function("f")
x=sp.Symbol('x')
eqn=sp.diff(f(
Thanks,
solved my problem!
