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. RcppArmadillo integrates this library with the R environment and language–and is widely used by (currently) 587 other packages on CRAN.
The (upstream-only again this time) changes are listed below:
Upgraded to Armadillo release 9.400.2 (Surrogate Miscreant)
.shed_slices()to remove rows/columns/slices specified in a vector
vectorise()to handle sparse matrices
expanded element-wise versions of
min()to handle sparse matrices
optimised handling of sparse matrix expressions:
sparse % (sparse +- scalar)and
sparse / (sparse +- scalar)
inv_sympd()to print a warning if the given matrix is not symmetric
more consistent detection of vector expressions
Courtesy of CRANberries, there is a diffstat report relative to previous release. More detailed information is on the RcppArmadillo page. Questions, comments etc should go to the rcpp-devel mailing list off the R-Forge page.
