-Armadillo is a C++ linear algebra library (matrix maths)
-aiming towards a good balance between speed and ease of use.
+Armadillo is a C++ linear algebra library (matrix maths).
 Integer, floating point and complex numbers are supported,
 as well as a subset of trigonometric and statistics functions.
-Various matrix decompositions are provided through optional
-integration with LAPACK and ATLAS libraries.
-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.
