Hi,
This sounds like a great idea. I think a symbolic circuit solver would
be a great
addition. You can think about implementing hints for the ode solver which
uses
laplace transforms to arrive at a solution (which was discussed previously).
The main difference between imitating SPICE is SPIC
Hi,
A symbolic circuit solver would use quite a bit of graph theory. Take a good
luck at NetworkX and how they do things. Any significant graph theory support
in SymPy should be consistent with what they do.
Good luck,
Tim.

I want to add a few things to sympy's matrices class such as image
and kernel of a matrix. Both of these are represented as the span of a set
of vectors.
Spans will normally take the form of span(v1,v2,v3...,vx) where all vs are
vectors of equal length.
I'm not exactly sure how to represent thes

As far as I read some papers about this, the Lie methods
become most powerful in the 2nd (and maybe higher) order
case. So I suggest that you consider also 2nd order
problems. No question any improvement on ODE solvers
is highly desirable.

@someone: Thanks a lot for your suggestion.
However, I believe even for first order differential equations, there is a
lot of work to be done. For solving the partial differential equation there
are a set of six algorithms, each having certain sub-algorithms , which I
guess in itself would take 1
I think that a project like this could tie in quite well with a separate
Lie group/lie algebra module, especially if we have something that would
store a lot of information about some of the most common Lie groups
(SL(2,C), SU(2), SO(3), etc).

Hello,
Pardon me for my ignorance, but my knowledge of lie groups is limited to
the solving of differential equations. However it seem a really good idea.
And I don't think that actual finding of lie groups is used in differential
equations, it is just the application that is used in finding

Hello all,
I was going through the project ideas for GSoC 2013 and I saw an entry for
implementation of vector calculus. As I have taken a semester's worth of
vector calculus, this looked like something I could do.
I am not saying that I'll be going with this proposal a 100%, but I may.
Anyway
I quite like Stefan's idea of a good API to the electrodynamics module,
once I am done building the infrastructure needed. How about something like
a sandbox?
I could do something like
S = new SandBox()
S.add(ElectricField1)
S.add(MagneticField1)
S.add(ChargedParticle1)
In this case, ChargedParti

Hello,
I'm new to sympy and I really like it. I have a question about code
generation. I want to generate code that works with a Matrix as an output
with the gradient of a function.
Is it possible to do something like this?
x = symbols('x:2', real=True)
x = symbols('x:2', real=True)
i = Idx('i
Thank you Jason, I'll look into the mechanics module and report back on
this thread soon.

Other places you might look for things that are already implemented
are the matrix and the differential geometry modules (including matrix
expressions).
There is also line_integrate, which uses Curve from the geometry
module. I believe that like the mechanics, the geometry module is
3-dimensional
Yeah, sure, let's try to advertise the high priority projects. We
could also restructure the ideas page to put the important ideas up
top. A general cleanup of the ideas page wouldn't hurt our chances
with the application to Google too. Any volunteers?

@Bharath : Thanks a lot for your input. I will think on the problem of
handling non-linear devices symbolically and will report back soon.
@Tim : I remember using NetworkX once while visualizing TSP, but will take
a thorough look at its codebase.

@moorepants, would like your input on the API idea. I want to finalize my
entire project idea before I start with my proposal.
@asmeurer, do you think I could get a mentor on this, considering no work
has been done in sympy in this direction till now?
