Courtesy of CRANberries, there is also a diffstat report for the most recent 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.Changes in RcppArmadillo version 0.4.000 (2014-01-05)
Upgraded to Armadillo release Version 4.000 (Feral Steamroller)
added eigen decompositions of sparse matrices:
eigs_sym()
andeigs_gen()
[ but this requires linking against ARPACK which RcppArmadillo as a pure-template package does not do, and R is not linked against ARPACK either. ]added eigen decomposition for pair of matrices:
eig_pair()
added simpler forms of
eig_gen()
added condition number of matrices:
cond()
expanded
find()
to handle cubesexpanded subcube views to access elements specified in a vector
template argument for
running_stat_vec
expanded to accept vector typesmore robust fast inverse of 4×4 matrices
faster divide-and-conquer decompositions are now used by default for
eig_sym()
,pinv()
,princomp()
,rank()
,svd()
,svd_econ()
the form
inv(sympd(X))
no longer assumes that X is positive definite; useinv_sympd()
insteadadded MEX connector for interfacing Octave/Matlab with Armadillo matrices (contributed by George Yammine)
