radical_inverse

Radical inverse ordering of the points of this rank-1 lattice

Specification

• Alias: None

• Arguments: None

Description

Returns the points in radical inverse order. This is the default setting.

Usage tips

The advantage of the radical inverse ordering is that one can generate a good point set with an arbitrary number of points \(N\).
