发帖数: 337 | 1 你需要个数学统计库函数， 如IMSL或者 numerical recipes
you do not want to write everything by yourself.
It is painful at first with debugging, but after that it should be fine.
I use Fortran (Compaq Visual Fortran, Intel Visual Fortran with IMSL),
not C/C++, but I think their computational power should be similar.
I once compared R and Fortran for one project
R: several hours (> 2.5)
Fortran: 1 min
Of course, I never care about optimization, as long as it works.
你说的这些函数，可以很方便地在LIBRARY中找到，如IMSL
