Conrad released a new upstream release 4.200 for Armadillo, his templated C++ library for linear algebra, earlier today.

As usual, this was rolled up in a new RcppArmadillo release; I had actually made two pre-releases leading up his 4.200 release and was hence not expecting any surprises. Prior to uploading to CRAN, I also tested against all 61 reverse dependencies of the package. Last but not least, I also updated the corresponding Debian package.

Changes in RcppArmadillo version (2014-04-07)

  • Upgraded to Armadillo release Version 4.200 (Flintlock Swoop)

    • faster transpose of sparse matrices

    • more efficient handling of aliasing during matrix multiplication

    • faster inverse of matrices marked as diagonal

Courtesy of CRANberries, there is also a diffstat report for the most recent 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.
