[sympy] Writing log bases using the latex printer?

As the question states - is there any way to write log bases in latex, rather than just writing "log"? -- You received this message because you are subscribed to the Google Groups "sympy" group. To unsubscribe from this group and stop receiving emails from it, send an email to sympy+unsubscr..

Re: [sympy] zoo*zoo == nan

I know this is not very helpful, but I am fairly certain we discussed this kind of subject, about two years ago, but never really reached a conclusion. The point is that of cours zoo+zoo should be nan (whereas it seems like zoo*zoo need not be, but perhaps that was never fixed). Tom On 25.02.

[sympy] Unbundle mpmath

There is a long term issue [1] to make mpmath an external dependency. It was suggested by Aaron (see discussion in PR [2]), that we should discuss this on the mailing list. Perhaps, the main reason to prefer bundled mpmath copy is a mystical "complex installation". Not clear enough. For examp

Re: [sympy] Unbundle mpmath

I am also of the opinion that we should unbundle it. Python has an extremely easy dependency tracking system and libraries can be easily installed without root privileges (with virtualenv and pip). Moreover, for the "lazy" scientists there are many pre-bundled python distributions ready to use. Eve

Re: [sympy] Re: Continued fraction representation of quadratic irrationalities

Yes, that is where it should go. I don't think it will be that hard to combine. There is a Java code that is used in Dario Alpern's website. I need the continued_fraction representation of quadratic irrational numbers in the Diophantine equation module. I

Okay, I want to contribute to release notes. But I am not sure if we can fix the issue of automation of release process in such a short time. Please tell me how can I help. I'll clone the doc repo now. -Saurabh On Friday, June 28, 2013 8:46:48 PM UTC+5:30, Aaron Meurer wrote: > > We are sprinti

Re: [sympy] Re: Continued fraction representation of quadratic irrationalities

One approach would be to have three inputs to continued_fraction() function corresponding to the general form of a quadratic irrational fraction (a + sqrt(b)) / c We can set b = 0 for other cases. But I think it is not a good approach. Another approach would be to keep the current interface of co

We're working on the release at SciPy2013. Please help by responding to this e-mail with a brief description of any contributions you (or others) have made since 0.7.2 (last October). Feel free to list contributions made by others. Alternatively you can add contributions directly to https://docs

Re: [sympy] Re: Continued fraction representation of quadratic irrationalities

Code segment I proposed should be changed as below. Otherwise it fails when sqrt()'s are not involved. def continued_fraction(a, b): p = Wild('p') q = Wild('q') r = Wild('r') a = Add(a) match = a.match(p + r*sqrt(q)) # and do the processing acc

And importantly, note all backwards incompatible changes. You can grep for SymPyDeprecationWarning to find things that are deprecated for the first time in this release. Aaron Meurer On Fri, Jun 28, 2013 at 11:56 AM, Matthew Rocklin wrote: > We're working on the release at SciPy2013. > > Please

[sympy] Simplifying simultaneous nonlinear equations

I'm contemplating using sympy in a program which will need to symbolically solve a set of simultaneous and possibly non-linear equations. However, it's obviously not possible to find symbolic solutions in many cases, but if sym.solve can't find an explicit solution what I'd really like is for s

Re: [sympy] Unbundle mpmath

Hi, We already agreed in the issue to allow to use systemwide version of mpmath, preferably by adding a simple switch to setup.py, while using our version of mpmath if the switch is not given. Patches would be appreciated. :) I vote yes to this. As far as physically removing sympy.mpmath, is the

You could solve for just two of the variables, like sym.solve((eq1, eq2, eq3), (z, x)). Aaron Meurer On Fri, Jun 28, 2013 at 3:56 PM, Ondřej Čertík wrote: > Hi Thomas, > > On Thu, Jun 27, 2013 at 8:32 PM, Thomas Moore wrote: >> I'm contemplating using sympy in a program which will need to symbo

Re: [sympy] Unbundle mpmath

@Sergey, I think Ondrej's point is that installing dependencies is not as easy as I have suggested. I guess this is open for debate. There is probably also a psychological barrier. `mpmath` is the only hard requirement for running sympy, and having it bundled permits the project to say that it has
