RcppArmadillo 0.5.500.2.0

armadillo image

Once again time for the monthly upstream Armadillo update -- version 5.500.2 was released earlier today by Conrad. And a new and matching RcppArmadillo release 0.5.500.2.0 in already on CRAN and will go to Debian shortly.

Armadillo is a powerful and expressive C++ template library for linear algebra aiming towards a good balance between speed and ease of use with a syntax deliberately close to a Matlab.

This release contains mostly bug fixes and some internal code refactoring:

Changes in RcppArmadillo version 0.5.500.2.0 (2015-09-03)

  • Upgraded to Armadillo 5.500.2 ("Molotov Cocktail")

    • expanded object constructors and generators to handle size() based specification of dimensions

    • faster handling of submatrix rows

    • faster clamp()

    • fixes for handling sparse matrices

Courtesy of CRANberries, there is also a diffstat report for the most recent CRAN release. As always, more detailed information is on the RcppArmadillo page. Questions, comments etc should go to the rcpp-devel mailing list off the R-Forge page.
