A new minor upstream release 4.100 of the Armadillo templated C++
library for linear algebra was finalised by Conrad yesterday.
I rolled up the corresponding RcppArmadillo
release 0.4.100.0 which is now on CRAN and will go to
Debian shortly.

Changes in RcppArmadillo version 0.4.100.0 (2014-02-28)

• Upgraded to Armadillo release Version 4.100.0 (Dirt Cruiser)

  • added normalise() for normalising vectors to unit p-norm

  • extended the field class to handle 3D layout

  • extended eigs_sym() and eigs_gen() to obtain eigenvalues of various forms (eg. largest or smallest magnitude)

  • automatic SIMD vectorisation of elementary expressions (eg. matrix addition) when using Clang 3.4+ with -O3 optimisation

  • faster handling of sparse submatrix views

  • workaround for a bug in LAPACK 3.4

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.
