**ProbNum** is a Python toolkit for solving numerical problems in linear algebra, optimization, quadrature and
differential equations. ProbNum solvers not only estimate the solution of the numerical problem, but also its uncertainty (numerical error) which arises from finite computational resources, discretization and stochastic input. This numerical uncertainty can be used in downstream decisions.Currently, available solvers are:
- **Linear solvers:** Solve $A x = b$ for $x$.
- **ODE solvers:** Solve $\dot{y}(t) = f(y(t), t)$ for $y$.
- **Integral solvers (quadrature):** Solve $F = \int_D f(x) \mathrm{d}p(x)$ for $F$.Lower level structure includes:
- **Random variables and random processes**, as well as arithmetic operations thereof.
- Memory-efficient and lazy implementation of **linear operators**.
- **Filtering and smoothing** for (probabilistic) state-space models, mostly variants of Kalman filters.ProbNum is underpinned by the research field probabilistic numerics (PN), which lies at the intersection of machine learning and numerics.
PN aims to quantify uncertainty arising from intractable or incomplete numerical computation and from stochastic input
using the tools of probability theory. The general vision of probabilistic numerics is to provide well-calibrated
probability measures over the output of a numerical routine, which then can be propagated along the chain of
computation.## Installation
To get started install ProbNum using `pip`.
```bash
pip install probnum
```
Alternatively, you can install the latest version from source.
```bash
pip install git+https://github.com/probabilistic-numerics/probnum.git
```> Note: This package is currently work in progress, therefore interfaces are subject to change.
