Conrad announced a new Armadillo release 6.600.4 yesterday. This followed some work we had done for thorough pre-release checking with reverse dependencies tests for the over 200 CRAN packages using it and resulted in one more squashed bug. This releasehas been folded into RcppArmadillo 0.6.600.4.0 which arrived on CRAN and Debian earlier today.
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.
Changes in this release are as follows:
Changes in RcppArmadillo version 0.6.600.4.0 (2016-03-15)
Upgraded to Armadillo 6.600.4 (Catabolic Amalgamator)
max()to handle cubes
Cubeclass to handle arbitrarily sized empty cubes (eg. 0x5x2)
shift()for circular shifts of elements
sqrtmat()for finding the square root of a matrix
gmm_diagwhen using Mahalanobis distance
configurescript now reflects the full LAPACK fallback offered by R 3.3.0 or later (PR #81)
Courtesy of CRANberries, there is also a diffstat report for this 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.
