Hi Eigen folks,

Eigen techniques are something that I long have wanted to learn more about but cannot find any appropriate materials around. I was simply going to suggest that perhaps, given your familiarity with the topic, you may consider writing several blog posts/tutorials covering a simple from scratch implementation of a matrix class that uses expression templates and SIMD optimizations? Or perhaps you can point me towards good learning materials on the subject?

About lazy evaluation, the best one (IMHO) is Eigen itself:
http://eigen.tuxfamily.org/dox/TopicLazyEvaluation.html
http://eigen.tuxfamily.org/dox/TopicIns ... ample.html

About the SIMD, itself, can't found a documentation here about it, but I can point you to Bullet code, it's esier than Eigen in order to understand SIMD:

Good luck!
