Introducing PyArmadillo: A Python Linear Algebra Library with Matlab‑Like Syntax
PyArmadillo is a newly released Python library that wraps the C++ Armadillo linear algebra package via pybind11, offering Matlab/Octave‑style syntax, extensive matrix and cube operations, high‑performance back‑ends, and easy installation on major operating systems for scientific computing.
Overview
PyArmadillo is a new Python linear algebra library built on the C++ Armadillo library and pybind11, offering Matlab/Octave‑like syntax for intuitive matrix operations.
Background
Python’s scientific stack (NumPy, SciPy) can be cumbersome for algebraic tasks; PyArmadillo addresses this by providing a simple, high‑level API while leveraging Armadillo’s performance.
Adoption of Armadillo
Armadillo is a widely used C++ scientific computing library adopted by organizations such as Facebook, NASA, Boeing, Siemens, Deutsche Bank, MIT, CMU, Stanford, and powers RcppArmadillo and the mlpack machine‑learning library.
Development
The library was developed in two months by Data61 interns Jason Rumengan (QUT) and Terry Yue Zhuo (UNSW) under the guidance of Armadillo’s lead author Conrad Sanderson.
Features
PyArmadillo provides matrix and cube objects, over 200 functions for data manipulation, supports integer, floating‑point and complex types, and integrates LAPACK, Intel MKL, or OpenBLAS for high‑performance decompositions.
Installation Guide
Requirements: Python ≥3.6 (3.8+ recommended), a C++11‑compatible compiler, at least 8 GB RAM, 64‑bit CPU (4+ cores), and pre‑installed OpenBLAS and LAPACK.
Supported operating systems: Linux, macOS, Windows x64 (no x86).
