Thanks a lot!
I will try to install it and if I run into trouble I'll take the liberty to
contact you again.
Best regards,

Hey Oscar,
SymEngine's lambdify can be used too. It uses numpy arrays to support
broadcasting
and other features of sympy.
from symengine import *
x = symbols('x')
e = x**2 + x
for _ in range(10):
e = e**2 + e
ed = e.diff(x)
f = lambdify([x], [ed])
print(f(.0001))
To avoid a bit of overhead

I'm sure it can be made faster. To be clear to anyone reading this
both SymEngine and protosym are using LLVM for this. I could h

It is and in some ways it is not realistic but actually in some ways
it is. A common case will certainly be small expressions e.g. for
simple ODEs as you show in the README. Another case thoug
That's right. This, or equivalently, `conda install -c conda-forge symjit`
should work on Windows, Linux, and MacOS. Even `python -m pip install
symjit` may work, but the conda route is preferable. However, there are
always corner cases. Please let me know if you have any problems.
It has three ma

Wow this is amazing. I have been thinking for a long tim
Hi Oscar,
Thank you very much for your response. I appreciate it. There is a lot to
think about.
Regarding the example, this is a tough test! It shows that there is a bug
in the x64-86 rust backend. Interestingly, the Python backend and the rust
one on ARM64 (MacOS) give the correct answer:
e =
Hi Oscar,
Yes, we can add symjit as another backend if it offers a C/C++ API.
We also have a pure C/C++ backend, just replace `LLVMDouble` by
`LambdaDouble`.
