Hello everyone!
I'm interested in contributing/working on Sage a bit. Specifically, one of
my Professor's came up with a faster way to compute q-digamma, at least in
some cases. I would like to code it up and add it to Sage. A few things are
in my way at the moment, that I wanted to ask about:
A few issues I am running into at the moment.
First, most of the functions in the other.py and special.py folder include
code for their derivatives. However, I honestly have no idea about the
derivative of the qgamma function, and I could not find any literature
about it. Is it possible to ha
You're certainly right. It was faster than mathematica implementation of
q-digamma, so I assumed that it would be faster than any implementation
that is open source. I will do some definitive testing of that soon. I
would like to add a basic implementation of these functions first at least.

I think Sage's integration can't compare to Mathematica's. The output is
not as clean and it doesn't solve as many integrals and it is not as fast.
Sage is used by many students, and in my opinion, its profitability and
sustainability in the future depends on classroom use, to a large extent.

Hey everyone:
So, here's the issue. I was facing this same issue before, so I decided to
delete my git folder in home and then install it again. So, I ran
git clone git://github.com/sagemath/sage.git
and it remade the sage directory. Then, I did "cd sage", and ran "git checkout
develop". Afte
So, I ran 'make distclean', and then I made sure that my develop branch was
up to date, and then I did make build and it ran properly and I was able to
do the doctest I had been trying to do before! Should I still run 'make'?
I'm kind of afraid that it will mess up again, it takes like 8-12 hour
I was on trac, looking at the tickets under "Bugs silently producing wrong
answers". All of them seemed quite old, for the most part, and none of
them(that I could find) had anything under Branch. Does this mean that they

What exactly are the benefits of using Python3? I thought that it tended to
be a bit slower for computation, since it uses infinite precision numbers
instead of ints. Not that I'm against it, I just didn't know the
motivation.

Hey everyone:
I was hoping some of you could provide some insight where my knowledge is
lacking. I'm trying to add to the M2/Sage interface by adding a conversion
for the M2 Divide class. Sage can already convert polynomials, so my hope
was to just have it treat the Divide class as two polynomi
Well, here's what i tried and it doesn't seem to work after I build sage
again. I added this code to the to_sage() function,
elif cls_str == "Divide":
self_Div = self
div_Numerator = macaulay2('numerator self_Div')
div_Denominator = maca
Hmm, so I tried this instead but it also didn't work and gave a similar
error:
elif cls_str == "Divide":
div_Str = repr_str
div_Numerator = macaulay2('numerator div_Str')
div_Denominator = macaulay2('denominator div_Str')
div_Numerator = div
Sorry! I hadn't seen that, that's great, thank you! The denominator is
proving to be a bit tricky to deal with, mostly because I can't decide what
I want to do with it. I did it though, but I'm not happy with it. I'm also

So, after fixing a small typo, here is the output from an example:

: A=matrix{{zet^1,0},{0,zet^14}}
: needsPackage "InvariantRing"
: G=generateGroup({A},K)
: P = molienSeries G

Thanks! That makes much more sense and seems simpler, I'm glad I know that
now!

Sorry about that, I thought sage-devel was for talking/asking questions

I'm not entirely sure how to implement this though, if we don't want it to
be the global behavior. I was considering just implementing it for the
rank() function, but I'm assuming it processes the input into the function
