Could you perhaps help me with a few pointers on how to use/test NT2 (e.g. performing sincos on a 1D vector)? I checked out the latest revision from SVN, and downloaded the documentation for the official version 2 but it is in French which I unfortunately do not understand. The examples for version 2 that contain the cos() function also do not work as they mention a nonexistent eve.hpp header...
We've been using git for a while, the svn version is quite outdated. The git version has documentation purely in English, except it's almost non-existent. I had started recently writing documentation separate from the code, but I quickly realized this was a huge amount of work, so I am looking into doxygen-based solutions atm (either boostbook or Sphinx with doxylink). I'm not giving you any examples yet, because the high-level SIMD code is undergoing lots of changes recently, and things like sincos (which returns a tuple) are broken when you use the Proto-based interface :(. I'll come back to you shortly.
ps. does NT2 support SSE1 for single precision floats? Unfortunately this is a must for me (and probably for a lot of people as there are quite a few Athlon XP's around) so I cannot use SSE2+ only libraries like Eigen...
I'm afraid not, it only supports SSE2 and upwards. But it could be a nice summer project to add support for SSE1 only... But seriously, who targets that kind of old CPU? ;)
