inlineconstexpr |
Range adaptor object that will apply std::get<N> to each value in the range lazily.
| N | Element to get from the array or tuple. |
| tuple | Tuple or array instance, with at least N + 1 elements. |

inlineconstexpr |
Range adaptor object that will insert values from a generator function between contiguous elements from the source based on a given probability.

inlineconstexpr |
Range adaptor object that will randomly sample with replacement from an input range. Unlike std::views::sample, this does not require a size parameter and the samples will be taken from the population with replacement, making the sample values independent. To use this, the input range must model the random_access_range and sized_range concepts.
This view implements multinomial resampling for a given range of particles. The core idea is to draw random indices / iterators to the input particle range from a multinomial distribution parameterized after particle weights (and assumed uniform for non-weighted particle ranges).
This view can also be used to convert any random distribution (a callable that takes a URNG as an input argument) into an infinite view that generates values from that distribution.
This view is not cheap to copy, so care must be taken when moving it around. Range-v3 does not support move-only views at the time of this implementation.

Range adaptor object that will obtain a reference to the state of each particle in the input range lazily.

|
inlineconstexpr |
Range adaptor object that will take elements evenly spaced over a range. Given a source range and an integral count, returns a range consisting of count elements evenly spaced over the source range. If count or the range size are zero, it returns an empty range. If count is greater than the range size, it returns all the elements. The first and last elements of the range are always included.

inlineconstexpr |
Range adaptor object that will take elements from a range while the KLD condition is statisfied. The input range should be randomly generated from an existing particle set. This adaptor will return elements until the minimum number of samples based on a Kullback-Leibler distance epsilon is satisfied.
