Description:

Armadillo is a streamlined 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. Optional integration with LAPACK and ATLAS libraries is also provided.

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:

Added functionality: - Cholesky and QR decompositions - element-wise division - comparison operators - more elegant restriction of template parameters

Bug fixes: - handling of diagonal matrices created from vectors - compilation of examples under MacOS X

Other changes: - faster matrix inverse - license change to LGPL v3+ - updated and re-arranged documentation
