Example 1

#include <stdio.h>
#include <codecogs/maths/special/bessel/y/y1.h>
int main()
{
  for(double x=1; x<7; x+=1)
  {
    double y=Maths::Special::Bessel::Y::Y1(x);
    printf("\n Y1(%.1lf)=%lf", x,y);
  }
  return 0;
}
Output:
Y1(1.0)=-0.781213
Y1(2.0)=-0.107032
Y1(3.0)=0.324674
Y1(4.0)=0.397926
Y1(5.0)=0.147863
Y1(6.0)=-0.175010
