Hello all,
A colleague at work set me the challenge to convert some MATLAB
code into R, to see which is faster. We'd seen that benchmark comparing
MATLAB 6.5 to R1.90 (and others), and so I thought that I should be able
to get roughly comparable speeds. The code has lots of multiplications
The first thing is to ensure that you are using an optimized BLAS. On
Windows, use Goto's BLAS if you have it (is not currently available and
redistribution is not allowed) or one of the pre-built ATLAS-based
Rblas.dll on CRAN or (best of all) optimize your own build of ATLAS.

The Matrix package is under active development and the documentation
has not caught up with the code. Examples of usage can be found in
the tests subdirectory of the source package. At present we are
concentrating on the class hierarchy and writing methods and test
cases for those methods.
