\item Upgraded to Armadillo release Version 4.000 (Feral Steamroller)
9
\item added eigen decompositions of sparse matrices:
10
\code{eigs_sym()} and \code{eigs_gen()}
11
\item added eigen decomposition for pair of matrices: \code{eig_pair()}
12
\item added simpler forms of \code{eig_gen()}
13
\item added condition number of matrices: \code{cond()}
14
\item expanded \code{find()} to handle cubes
15
\item expanded subcube views to access elements specified in a vector
16
\item template argument for \code{running_stat_vec} expanded to
18
\item more robust fast inverse of 4x4 matrices
19
\item faster divide-and-conquer decompositions are now used by
20
default for \code{eig_sym()}, \code{pinv()}, \code{princomp()},
21
\code{rank()}, \code{svd()}, \code{svd_econ()}
22
\item the form \code{inv(sympd(X))} no longer assumes that X is
23
positive definite; use \code{inv_sympd()} instead
24
\item added MEX connector for interfacing Octave/Matlab with
25
Armadillo matrices (contributed by George Yammine)
