function template

std::sinh

<valarray>
template<class T> valarray<T> sinh (const valarray<T>& x);
Compute hyperbolic sine of valarray elements
Returns a valarray object containing the hyperbolic sines of all the elements of x.

This function overloads cmath's sinh function.

Parameters

x
valarray containing elements of a type for which the unary function sinh is defined.

Return value

A valarray object with the hyperbolic sine values of the elements of x.

// sinh valarray example
#include <iostream>
#include <cmath>
#include <valarray>
using namespace std;

int main ()
{
  double val[] = {0.35, 1.22, 3.4};
  valarray<double> foo (val,3);

  valarray<double> bar = sinh (foo);

  cout << "foo: ";
  for (size_t i=0; i<foo.size(); ++i)
	  cout << foo[i] << ' ';
  cout << endl;

  cout << "bar: ";
  for (size_t i=0; i<bar.size(); ++i)
	  cout << bar[i] << ' ';
  cout << endl;

  return 0;
}


Output:

foo: 0.35 1.22 3.4
bar: 0.35719 1.54598 14.9654
