Package: r-cran-rcpparmadillo (15.0.2-1-1)

GNU R package for Armadillo C++ linear algebra library

Armadillo is a templated C++ linear algebra library aiming towards a good balance between speed and ease of use. It provides high-level syntax and functionality deliberately similar to Matlab. It is useful for algorithm development directly in C++, or quick conversion of research code into production environments. It provides efficient classes for vectors, matrices and cubes where 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 are provided through integration with LAPACK, or one of its high performance drop-in replacements (such as MKL or OpenBLAS). It can automatically use 'OpenMP' multi-threading (parallelisation) to speed up computationally expensive operations.

The RcppArmadillo package includes the header files from the Armadillo library; users do not need to install Armadillo itself in order to use RcppArmadillo. Starting from release 15.0.0, the minimum compilation standard is C++14 so Armadillo version 14.6.3 is included as a fallback when an R package forces the C++11 standard. Package authors should set a '#define' to select the 'current' version, or select the 'legacy' version (also chosen as default) if they must. See 'GitHub issue #475' for details.
