this is generally reasonably it makes sense here to continue which
the Moore-Penrose pseudo-inverse allows us to do this

types such as an arma::mat and an arma::imat, which have been introduced
in armadillo 0.9.10
o Included an inline plugin to support the plugin system introduced
in inline 0.3.5. The unit tests have moved from the src directory
to the unit test directory (similar to Rcpp) using cxxfunction with the
RcppArmadillo plugin.
0.2.1 2010-05-19
o Bug-fix release permitting compilation on Windows
0.2.0 2010-05-18
o fastLm() is now generic and has a formula interface as well as
methods for print, summary, predict to behave like a standard
model fitting function
o Armadillo sources (using release 0.9.8) are now included in the
package using a standardized build suitable for our purposes
(not assuming Boost or Atlas) -- see ?RcppArmadillo for
details
o New R function RcppArmadillo.package.skeleton, similar to
Rcpp::Rcpp.package.skeleton, but targetting use of
RcppArmadillo
0.1.0 2010-03-11
o the fastLm() implementation of a bare-bones lm() fit (using
Armadillo's solve() function) provides an example of how
efficient code can be written compactly using the combination
of Rcpp, RcppAramadillo and Armadillo
o support for Rcpp implicit wrap of these types :
Mat<T>, Col<T>, Row<T>, Cube<T> where T is one of :
int, unsigned int, double, float
o support for Rcpp implicit as of these types :
Mat<T>, Col<T>, Row<T> where R is one of :
int, unsigned int, double, float
Computing file changes ...
