A second Armadillo release 6.700.6 came out in the 6.700 series, and we uploaded RcppArmadillo 0.6.700.6.0 to CRAN and Debian. This followed the usual thorough reverse-dependecy checking of by now 220 packages using.

This release is a little unusual in that it contains both upstream bugfixes in the same series (see below) but also two nice bug fixes from the RcppArmadillo side. Both were squashed by George G. Vega Yon via two focused pull request. The first ensures that we can now use ARMA_64BIT_WORD (provided C++11 is turned on too) allowing for much bigger Armadillo objects. And the second plugs a small leak in the sparse matrix converter I had added a while back. Nice work, all told!

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 0.6.700.6.0 (2016-05-05)

  • Upgraded to Armadillo 6.700.6 (Catabolic Amalgamator Deluxe)

    • fix for handling empty matrices by kron()

    • fix for clang warning in advanced matrix constructors

    • fix for false deprecated warning in trunc_log() and trunc_exp()

    • fix for gcc-6.1 warning about misleading indentation

    • corrected documentation for the solve() function

  • Added support for int64_t (ARMA_64BIT_WORD) when required during compilation time. (PR #90 by George G. Vega Yon, fixing #88)

  • Fixed bug in SpMat exporter (PR #91 by George G. Vega Yon, fixing #89 and #72)

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.
