This release upgrades the included Armadillo version to 0.9.52
(see here for Conrad's high-level changes).
We had to make two minor tweaks. In the fastLm()
help page example we switched from inv() to pinv()
The short NEWS file extract follows:
0.2.4 2010-07-27
o Upgraded to Armadillo 0.9.52 'Monkey Wrench'
o src/fastLm.cpp: Switch from inv() to pinv() as inv() now tests for
singular matrices and warns and returns an empty matrix which stops
the example fastLm() implementation on the manual page -- and while
this is generally reasonably it makes sense here to continue which
the Moore-Penrose pseudo-inverse allows us to do this
