pydiffsol

Python bindings for diffsol

Example usage

import pydiffsol as ds
import numpy as np

ode = ds.Ode(
    """
    r { 1.0 }
    k { 1.0 }
    u { 0.1 }
    F { r * u * (1.0 - u / k) }
    """,
    ds.nalgebra_dense_f64
)
p = np.array([])
print(ode.solve(p, 0.4))

Local development

To build locally, use maturin and set diffsol-llvm feature to your installed LLVM. Also specify dev extras for pytest, running examples and docs image generation. For example:

maturin develop --extras dev --features diffsol-llvm17

The included .vscode include examples for running tests and examples in python and rust debuggers. The config works with diffsol-llvm17 by default and assumes that you have it already installed, for example on macos with brew install llvm@17 or for debian-flavoured linux apt install llvm-17.
