Description:

Armadillo is a template C++ linear algebra library (matrix maths) aiming towards a good balance between speed and ease of use. Integer, floating point and complex numbers are supported, as well as a subset of trigonometric and statistics functions. Various matrix decompositions are provided via an optional integration with LAPACK, or one of its high performance drop-in replacements (e.g. AMD's ACML or Intel's MKL).

A delayed evaluation approach is employed (during compile time) to combine several operations into one and reduce (or eliminate) the need for temporaries. This is accomplished through recursive templates and template meta-programming.

This library is useful if C++ has been decided as the language of choice (due to speed and/or integration capabilities), rather than another language like Matlab or Octave. It is distributed under a license that is useful in both open-source and commercial contexts.

Changes to previous version:

• faster handling of compound expressions with submatrices and subcubes
• added support for loading matrices as text files with NaN and Inf elements
• added stable_sort_index(), which preserves the relative order of elements with equivalent values
• added handling of sparse matrices by mean(), var(), norm(), abs(), square(), sqrt()
• added saving and loading of sparse matrices in arma_binary format
