Armadillo is a c++++ linear algebraic library (matrix mathematics) with balanced speed and ease of use for all operating platforms, including Linux, Mac OS X, and Windows. Its function is to support integers, floating-point numbers, and complex digits, as well as subsets of trigonometric functions and statistics, to provide a variety of matrix decomposition through the integration of optional lapack and Atlas libraries. The deferred evaluation method is based on template metaprogramming, which is used to combine several operations at compile time into one and reduce or eliminate the need for temporary variables.
