The recent 0.9.400.2.0 release of RcppArmadillo required a bug fix release. Conrad follow up on Armadillo 9.400.2 with 9.400.3 – which we packaged (and tested extensively as usual). It is now on CRAN and will get to Debian shortly.
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) 597 other packages on CRAN.
A brief discussion of possibly issues under 0.9.400.2.0 is at this GitHub issue ticket. The list of changes in 0.9.400.3.0 is below:
Changes in RcppArmadillo version 0.9.400.3.0 (2019-05-09)
Upgraded to Armadillo release 9.400.3 (Surrogate Miscreant)
check for symmetric / hermitian matrices (used by decomposition functions) has been made more robust
logspace()now honour requests for generation of vectors with zero elements
fix for vectorisation / flattening of complex sparse matrices
The previous changes in 0.9.400.2.0 were:
Changes in RcppArmadillo version 0.9.400.2.0 (2019-04-28)
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.
