A new Armadillo release 6.700.3 is out, and we uploaded RcppArmadillo 0.6.700.3.0 to CRAN and Debian. This followed the usual thorough reverse-dependecy checking of by now 216 packages using.

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 0.6.700.3.0 (2016-04-05)

• Upgraded to Armadillo 6.700.3 (Catabolic Amalgamator Deluxe)

  • added logmat() for calcuating the matrix logarithm

  • added regspace() for generating vectors with regularly spaced elements

  • added logspace() for generating vectors with logarithmically spaced elements

  • added approx_equal() for determining approximate equality

  • added trapz() for numerical integration

  • expanded .save() and .load() with hdf5_binary_trans file type, to save/load data with columns transposed to rows

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.
