Function template scatter_if

boost::compute::scatter_if

Synopsis

// In header: <boost/compute/algorithm/scatter_if.hpp>


template<typename InputIterator, typename MapIterator, 
         typename StencilIterator, typename OutputIterator, 
         typename Predicate> 
  void scatter_if(InputIterator first, InputIterator last, MapIterator map, 
                  StencilIterator stencil, OutputIterator result, 
                  Predicate predicate, 
                  command_queue & queue = system::default_queue());

Description

Copies the elements from the range [first, last) to the range beginning at result using the output indices from the range beginning at map if stencil is resolved to true. By default the predicate is an identity

Space complexity: \Omega(1)
