Template Function thrust::min_element(ForwardIterator, ForwardIterator)

Function Documentation

template<typename ForwardIterator>
ForwardIterator thrust::min_element(ForwardIterator first, ForwardIterator last)

min_element finds the smallest element in the range [first, last). It returns the first iterator i in [first, last) such that no other iterator in [first, last) points to a value smaller than *i. The return value is last 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 using operator<. Specifically, this version of min_element returns the first iterator i in [first, last) such that, for every iterator j in [first, last), *j < *i is false.

#include <thrust/extrema.h>
...
int data[6] = {1, 0, 2, 2, 1, 3};
int *result = thrust::min_element(data, data + 6);

// result is data + 1
// *result is 0
Return

An iterator pointing to the smallest element of the range [first, last), if it is not an empty range; last, otherwise.

Parameters

  • first: The beginning of the sequence.

  • last: The end of the sequence.
