[sympy] complex numbers

Something that seems a little counter-intuitive to me (having now worked with the assumptions a bit) is the decision to let 2, I and 2 + I all be considered complex (with the former two being real and imaginary, also, respectively). It seems like it would be more useful to consider them be onln

Matt, I think the individual pieces may be a great way to go. I was looking at SymPy's matrix code and was curious if that supports symbolic computation right now or is it only numeric? As for some of the individual pieces, I think the following are important concepts needed in financial statist

Hi Chase, Thanks for your interest. Many of the topics you bring up are definitely of interest to us. In my experience students who present and run with their own topics often produce good results, so, if you have a particular interest in quantitative finance then it's good to push on that. How

We can also submit the SymPy tutorial again. I'll do it if someone else is willing to help (I don't really want to give a four hour tutorial by myself). Regarding talks, probably any of the GSoC projects from last year are talk worthy (though probably best by the person who did the project). Aaro

[sympy] Re: GSoC: Introducing Optical Physics

I have to agree with Stefan here. In optics, the usual manipulations and calculations are better done with a simple matrix - though if we need to express vectors/coordinates in different systems, you could use the vector API- but that would just be the minimal use. The core operations would be

Re: [sympy] Re: GSoC: Introducing Optical Physics

Stefan, The physics.vector package provides vectors and tensors that are basis dependent which eases working with vectors defined in multiple reference frames that are rotated with respect to each other. If all of your vectors are defined in a single reference frame, then column matrices suffice.

I would suggest you to go through the API of physics.vector package and see if you have all the functionality you need. I think you should. Once you have done that, you can start thinking of how you will base your work on that module, the target API, etc. Once you have some idea, you can start
