功能
| iota (C++11) | fills a range with successive increments of the starting value (function template) |
|---|---|
| accumulate | sums up a range of elements (function template) |
| reduce (C++17) | similar to std::accumulate, except out of order (function template) |
| transform_reduce (C++17) | applies a functor, then reduces out of order (function template) |
| inner_product | computes the inner product of two ranges of elements (function template) |
| adjacent_difference | computes the differences between adjacent elements in a range (function template) |
| partial_sum | computes the partial sum of a range of elements (function template) |
| inclusive_scan (C++17) | similar to std::partial_sum, includes the ith input element in the ith sum (function template) |
| exclusive_scan (C++17) | similar to std::partial_sum, excludes the ith input element from the ith sum (function template) |
| transform_inclusive_scan (C++17) | applies a functor, then calculates inclusive scan (function template) |
| transform_exclusive_scan (C++17) | applies a functor, then calculates exclusive scan (function template) |
| gcd (C++17) | constexpr function template returning the greatest common divisor of two integers (function template) |
| lcm (C++17) | constexpr function template returning the least common multiple of two integers (function template) |
