Peroxide
Rust numeric library contains linear algebra, numerical analysis, statistics and machine learning tools with R, MATLAB, Python like macros.
Why Peroxide?
1. Customize features
Peroxide provides various features.
default
- Pure Rust (No dependencies of architecture - Perfect cross compilation)O3
- SIMD + OpenBLAS (Perfect performance but hard to set-up - Strongly recommend to read OpenBLAS for Rust)plot
- With matplotlib of python, we can draw any plots.dataframe
- Dataframe & netcdfserde
- serialization with Serde.
If you want to do high performance computation, then choose openblas feature. If you don't want to depend C/C++ or Fortran libraries, then choose default feature. If you want to draw plot with some great templates, then choose plot feature.
You can choose any features simultaneously.
2. Easy to optimize
Peroxide uses 1D data structure to describe matrix. So, it's too easy to integrate BLAS & SIMD. It means peroxide guarantees perfect performance for linear algebraic computations.
3. Friendly syntax
Rust is so strange for Numpy, MATLAB, R users. Thus, it's harder to learn the more rusty libraries. With peroxide, you can do heavy computations with R, Numpy, MATLAB like syntax.
For example,
extern crate peroxide;
use *;
4. Batteries included
Peroxide can do many things.
- Linear Algebra
- Effective Matrix structure

5. Written in Rust
Rust & Cargo are awesome for scientific computations. You can use any external packages easily with Cargo, not make. And default runtime performance of Rust is also great. If you use many iterations for computations, then Rust become great choice.
