Hi
I am a second year undergraduate student of Information Systems from BITS

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
To get started should I add a module to solve problems related to Kepler's
laws? It will give me a basic idea of physics.vector.

Sudhanshu,
Thanks for your interest. I think it would be best to propose this project
on the SymPy mailing list (I've cc'd it), as it doesn't have to do with
multibody dynamics (PyDy's purpose). This could be a nice addition to the
physics capabilities in SymPy and if you needed to modify or
Why is physics.vector better for optics compared to just a column matrix?

Is this project doable withing the summer duration?
If we consider adding only necessary things, it should not hinder the next
major release of sympy.

Hi Stefan
Using physics.vector will make this work easier. It's always possible to do
it without the vector. Not using vector will reduce the readability of the
code.

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 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

@Sachin not really extensive but vectors are frequently used in the optics.
If there's no issue, I'll use matrix only.
But my question wasn't vector or matrix. Please give me suggestions on how
should I proceed with the idea. Can anyone mentor this project, if this
idea feels promising?

Read the literature on the Karr Algorithm. There is not so much.
You can start with the two original papers by M. Karr.

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.
I'm pretty certain I will be able to come and can help run the SymPy
tutorial if so. But, of course couldn't if it time clashed with the PyDy
one (if it gets accepted). Anyways, count me in to help in the tutorial.

SymPy's matrix code and was curious if that supports symbolic computation

respectively). It seems like it would be more useful to consider them be
