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
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.
