public member function

std::slice::slice

default (1)	slice();
initialization (2)	slice (size_t start, size_t length, size_t stride);
copy (3)	slice (const slice& x);

slice constructor

Constructs a slice object.

Parameters

start: Index of the first element in the slice.
The index of the first element in a valarray is 0 (not 1).
length: Number of elements in the slice.
stride: Span that separate the elements selected into the slice.
x: Slice object (copy constructor).

size_t is an unsigned integral type.

Example

// slice::slice example
#include <iostream>     // std::cout
#include <cstddef>      // std::size_t
#include <valarray>     // std::valarray, std::slice

int main ()
{
  std::valarray<int> foo (12);
  for (int i=0; i<12; ++i) foo[i]=i;

  std::slice first;
  std::slice second (2,3,4);
  std::slice third (second);

  std::valarray<int> bar = foo[third];

  std::cout << "bar contains:";
  for (std::size_t n=0; n<bar.size(); n++)
	  std::cout << ' ' << bar[n];
  std::cout << '\n';

  return 0;
