Hi Q gods,I have a C++ program which required heavy memory lifting to be
"prepared". After it is done all those heavy lifting, the preceding
calculation is however very fast.Looking at the C API, it seems that I
can only return primitive types back i...
Hi Q Gods,Is there any trick to avoid using each?I found out this by
implementing simple normal inverse function that each is fairly slow to
use. It seems that one should avoid each as much as possible to take
leverage of the vectorisation in Q.Howev...

actually I tried to implement it today. This augmented solution is a
beast. The only concern I have is that essentially we are trading off
between speed and memory.But I guess this is the most Q way of doing it.
This would hide the interface but in terms of the computational
intensity it is the really the same isn't it?For normal and its inverse,
i used rational approximation so the code can be easily vectorised.It
seems there is no other way in this case. (...
