A new RcppArmadillo release is now out, below is a text copy (without links)
of what is at http://dirk.eddelbuettel.com/blog/
RcppArmadillo 0.3.900.0
A Armadillo release 3.900.0 was provided by Conrad yesterday. It has been
rolled into a new RcppArmadillo release 0.3.900.0 which is now on CRAN and
in Debian.
It has a number of nice changes, mostly on the performance side of things
(see below) and a minor cleanup/improvement in our Kalman filter example
(which, as I just realized, I forgot to note in the \code{NEWS.Rd} in the
released tarball):
Changes in RcppArmadillo version 0.3.900 (2013-06-04)
* Upgraded to Armadillo release Version 3.900.0 (Bavarian Sunflower)
* added automatic SSE2 vectorisation of elementary expressions
(eg. matrix addition) when using GCC 4.7+ with -O3 optimisation
* added support for saving & loading of cubes in HDF5 format,
contributed by Szabolcs Horvat
* faster median(), contributed by Ruslan Shestopalyuk
* faster handling of compound expressions with transposes of
submatrix rows
* faster handling of compound expressions with transposes of
complex vectors
* Kalman filter example switched from inline to \code{sourceCpp},
which simplifies / streamlines the C++ side a little
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.
