inlinestatic

Construct a Impl<Kokkos::HostSpace> and associated discrete_domain_type from a segment \([a, b] \subset [a, +\infty[\) and a number of points n.

Note that there is no guarantee that either the boundaries a or b will be exactly represented in the sampling. One should expect usual floating point rounding errors.

Parameters

a	coordinate of the first point of the domain
b	coordinate of the last point of the domain
n	number of points to map on the segment \([a, b]\) including a & b
n_period	the number of steps in a period

Parameters
