Dop4d16< Type > Class Template Reference

Detailed Description

template<class Type>
class Dop4d16< Type >

16-plane discrete polytope in 4D.

A four-dimensional 32-DOP.

Todo:

Implementation note: pcoef() is not optimized away, which means that c[16] (stack) is actually filled and read again once, resulting in a lot of uneccessary mov instructions. Need to find an alternative implementation which guarantees inlining.
