Hi everyone,
I have a slight issue with the matrix product evaluated on lazy tensors. Let's `K` is a [N, M] matrix - the result of a distance function on inputs `x` and `y` with shapes [N, 1] and […

I ran a few experiments and the results look pretty good. Let's go for the fun polyphony part? :smile:

### Description
Since the riemann zeta function is very interesting in the critical strip of Re(s)=1/2 I think it would be very useful to implement a very fast method to evaluate zeta on that strip. …

Currently, one can emulate the Iverson Bracket in this way:
```python
def IversonBracket(expr):
return Piecewise((1, expr),(0,True))
```
which looks the following way when pretty-printed:

Recently, a Control Systems package was added to SymPy as [_sympy.physics.control_](https://github.com/sympy/sympy/tree/master/sympy/physics/control). It would be nice to add graphical analyses to it.…

I am getting a Pardiso crash if I use JuMP at the same time, but it seems to depend on the order of package inclusion. Example is below. If I do `using JuMP` before `using Pardiso`, I get a crash,…

The current Jacobian helper function implementation in `gradient.py` seems like it might be slower than it needs to be. Given a vector output (size _N_) of a graph with a vector input (size _M_), it c…

We intend to implement asymptotic expansions in SageMath. We would like to do computations with simple expansions such as
n2 + n3/2 + O(n1/2),
but also with expansions such as
2n * n + O(n*log(n)…
