## Function unique

boost::compute::unique

## Synopsis

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

    template<typename InputIterator, typename BinaryPredicate>
      InputIterator
      unique(InputIterator first, InputIterator last, BinaryPredicate op,
             command_queue & queue = system::default_queue());
    template<typename InputIterator>
      InputIterator
      unique(InputIterator first, InputIterator last,
             command_queue & queue = system::default_queue());

## Description

Removes all consecutive duplicate elements (determined by `op`) from the range [first, last). If `op` is not provided, the equality operator is used.

Parameters: |
`first` | first element in the input range
`last` | last element in the input range
`op` | binary operator used to check for uniqueness
`queue` | command queue to perform the operation
Returns: | `InputIterator` to the new logical end of the range
