C++ library for linear algebra & scientific computing (original) (raw)

• Armadillo is a high quality linear algebra library (matrix maths) for the C++ language, aiming towards a good balance between speed and ease of use
• Provides high-level syntax and functionality deliberately similar to Matlab
• Useful for algorithm development directly in C++, or quick conversion of research code into production environments
• Provides efficient classes for vectors, matrices and cubes; dense and sparse matrices are supported
• Integer, floating point and complex numbers are supported
• A sophisticated expression evaluator (based on template meta-programming) automatically combines several operations to increase speed and efficiency
• Dynamic evaluation automatically chooses optimal code paths based on detected matrix structures
• Matrix decompositions (eigen, SVD, Cholesky, etc) are provided through integration with LAPACK, or one of its high performance drop-in replacements (eg. MKL or OpenBLAS)
• Can automatically use OpenMP multi-threading (parallelisation) to speed up computationally expensive operations
• Distributed under the permissive Apache 2.0 license, useful for both open-source and proprietary (closed-source) software
• Can be used for machine learning, pattern recognition, computer vision, signal processing, bioinformatics, statistics, finance, etc
