A new major release 4.000 of Armadillo
came out out yesterday morning. This is a new stable release by
Conrad with a new major
number, and it brings a few nice changes as detailed below.
I rolled up RcppArmadillo
version 0.400 yesterday morning, and following a little bit of discussion
this version is now on CRAN
and in Debian.
The complete list of changes is below.
Changes in RcppArmadillo version 0.4.000 (2014-01-05)
Upgraded to Armadillo release Version 4.000 (Feral Steamroller)
added eigen decompositions of sparse matrices:
eigs_gen()[ but this requires
linking against ARPACK which RcppArmadillo as a
pure-template package does not do, and R is not linked against
ARPACK either. ]
added eigen decomposition for pair of matrices:
added simpler forms of
added condition number of matrices:
find()to handle cubes
expanded subcube views to access elements specified in a vector
template argument for
running_stat_vecexpanded to accept vector types
more robust fast inverse of 4×4 matrices
faster divide-and-conquer decompositions are now used by default
inv(sympd(X))no longer assumes that X is positive definite; use
added MEX connector for interfacing Octave/Matlab with Armadillo matrices (contributed by George Yammine)
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.
