Hi everyone,

I've just released Armadillo 1.99.5, which is likely to get wrapped up
in the next release of RcppArmadillo.
See http://arma.sourceforge.net/

The 1.99.x series are beta releases for the upcoming 2.0 release.

There are a few minor but important API changes and additions in
1.99.5, elaborated below:

API changes:

Forms of decomposition/inverse/solver functions that do not return a
bool indicating success will now throw std::runtime_error exceptions
when failures are detected  Affected functions: chol(), eig_sym(),
eig_gen(), inv(), lu(), pinv(), princomp(), qr(), solve(), svd(),

princomp_cov() has been removed as it was a superfluous function.
princomp() in conjunction with cov() can be used instead.

set_log_stream() and get_log_stream() have been replaced by
set_stream_err1() and get_stream_err1().

API additions:

det(), inv() and solve() can be forced to use more precise algorithms
for tiny matrices (sizes <= 4x4).

Added loading & saving of matrices as CSV text files.
