From the far distance - maybe it's worth considering trying to make
Eigen a default option for open-source optimized blas / lapack
libraries? The whole world of numerical open-source packages is
really suffering at the moment for lack of reliable and easy-to-build
options on Windows [1], and on OSX [2]. If you think Eigen might be
competitive as a general blas / lapack library (cf ATLAS, MKL etc),
and it was possible to build on Windows, then my guess is you'd have a
lot of interest and support from us numerical packages people...
I'm not the expert on this, but I think Eigen's BLAS implementation is
almost feature complete (very few Fortran functions left, which could
easily be implemented in C/C++ if someone cared). And we are definitely
at least competitive with other BLAS/LAPACKs
(http://eigen.tuxfamily.org/index.php?title=Benchmark -- these require
an update, but cf recent comparisons with Blaze on the mailing list and
in bugzilla)
For LAPACK I think we only have very few things implemented natively (I
only found cholesky, lu and eigenvalues)
The relevant bugzilla entries are:
http://eigen.tuxfamily.org/bz/show_bug.cgi?id=61
http://eigen.tuxfamily.org/bz/show_bug.cgi?id=62
Assuming we finished those, what would be the next steps to become a
"default option"? I.e., adaptions to our build-system, how/where to
publish and announce, ...
Overall, I think Eigen could really profit from more feedback and
contributions by numerical experts!
