Name        : armadillo
Product     : Fedora 21
Version     : 4.450.0
Release     : 1.fc21
URL         : http://arma.sourceforge.net/
Summary     : Fast C++ matrix library with interfaces to LAPACK and ATLAS
Description :
Armadillo is a 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 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.

Update Information:

This release has several improvements and fixes:

 * faster handling of matrix transposes within compound expressions
 * expanded symmatu()/symmatl() to optionally disable taking the complex conjugate of elements
 * expanded sort_index() to handle complex vectors
 * expanded the gmm_diag class with functions to generate random samples
 * faster handling of subvectors by dot()
 * faster handling of aliasing by submatrix views
 * expanded batch insertion constructors for sparse matrices to add values at repeated locations
 * added clamp() for clamping values to be between lower and upper limits
 * added gmm_diag class for statistical modelling using Gaussian Mixture Models (GMM);
 * includes multi-threaded implementation of k-means clustering and Expectation Maximisation (EM) algorithms
