Rcpp? #1

Open mmaechler opened 3 years ago

Is it necessary for you to use Rcpp instead of plain C (which is rather faster than slower)? I'm asking because this will make any back porting to Matrix impossible, AFAICS.

Rcpp is not really required, but unfortunately C++ is, since it brings some benefits that do make a difference in timings:

Also makes it easier to have functions for different types using templates, compared to putting C functions in headers and playing with macros.

But there's of course workarounds for them, with some penalty in complexity and speed.
