How is that a bad thing? Python is already used heavily for numeric
computations.
It's good for this specific domain, but bad for the Python in general,

Yes, that's very *big* amount of work. btw, I think now (see pr #2630)
Yes, that's very *big* amount of work.
You mean enough for the summer
or too much for the summer?
Since this project involves several sub-projects as per your suggestion
I should focus on:
1) formal power series
2) asymptotic expansion
3) some functions in polys module
right?

There are a few problems -
The Operator has been represented in such a way that for it to act on
bra/ket we have to use (*).
Instead we can define Operator as a function where we pass the bra/ket
.This function can store the values (for calculation) and then we can print
the notation

There *is* this in NumPy (which is the main use-case for this PEP):
numpy.matrix. But it causes headaches for everyone who uses it.

That's a great reference. Can you put that on the ideas page, if it

Hi,
Theano is participating to GSoC via the PSF this year. In our ideas
list, some of them would be very useful to PyDy/SymPy users. So I
would like to bring discuss them with you.
Matthew R. did a converter from SymPy graph to Theano. This
I've added them.

They both sound like great ideas. We can certainly provide large scalar
functions for testing #1. I'd also like to dispatch our `solve()` methods
to Theano in the pydy-code-gen source. #2 is interesting, we could use
something like that to generate fast ODE evals that can then be wrapped
under a
I obviously think that SymPy-Theano interactions are interesting. My
series of blogposts on that topic continue to get decent web traffic today.
For what it's worth I'm also happy to vouch for Frederic and the Theano
crew. They're a good group with which to collaborate.
