thrust::min_element
Defined in thrust/extrema.h
-
template<typename DerivedPolicy, typename ForwardIterator>
ForwardIterator thrust::min_element(const thrust::detail::execution_policy_base<DerivedPolicy> &exec, ForwardIterator first, ForwardIterator last) min_element
finds the smallest element in the range[first, last)
. It returns the first iteratori
in[first, last)
such that no other iterator in[first, last)
points to a value smaller than*i
. The return value islast
if and only if[first, last)
is an empty range.The two versions of
min_element
differ in how they define whether one element is less than another. This version compares objects usingoperator<
. Specifically, this version ofmin_element
returns the first iteratori
in[first, last)
such that, for every iteratorj
in[first, last)
,*j < *i
isfalse
.The algorithm’s execution is parallelized as determined by
exec
.#include <thrust/extrema.h> #include <thrust/execution_policy.h> ... int data[6] = {1, 0, 2, 2, 1, 3}; int *result = thrust::min_element(thrust::host, data, data + 6); // result is data + 1 // *result is 0
- Parameters
exec – The execution policy to use for parallelization.
first – The beginning of the sequence.
last – The end of the sequence.
- Template Parameters
ForwardIterator – is a model of Forward Iterator, and
ForwardIterator's
value_type
is a model of LessThan Comparable.- Returns
An iterator pointing to the smallest element of the range
[first, last)
, if it is not an empty range;last
, otherwise.
