About:
Armadillo is a high-quality C++ linear algebra library aiming towards a good balance between speed and ease of use. It provides a clean, MATLAB-like syntax for matrix operations and supports various decompositions. It is widely used in machine learning, computer vision, and scientific computing applications.
Key Features:
  • MATLAB-like syntax for intuitive matrix manipulation
  • Supports various matrix decompositions (SVD, eigendecomposition, etc.)
  • Can leverage LAPACK and BLAS for high performance
  • Header-only design for easy integration
Use Cases:
  • Machine learning algorithm prototyping
  • Computer vision and image processing
  • Scientific and engineering simulations
Alternatives:
  • Eigen – Eigen is often faster for fixed-size matrices and expression templates, while Armadillo offers a more familiar MATLAB-like syntax.
  • Blaze – Blaze focuses on high-performance computing and parallelism, whereas Armadillo prioritizes ease of use and readability.
