Thanks for your swift reply.
Yes,it is of the same size, I must change the line
std::vectorQuantLib::Time yearfracs(subsample.size())
Thanks again

Dear Users, I am using a pointer to a function member with the std::transform alorithm. The class is a QuantLib class called DayCounter and the method is called yearFraction and takes in two mandatory dates and two optionals to return the corresponding year fraction. /yearFraction ( QuantLib::Date t1,QuantLib::Date t2,QuantLib::Date t3 = Date(),QuantLib::Date t4=Date())/ Now I tried to fill a vector called yearfracs in this way boost::shared_ptrQuantLib::DayCounter dc( new QuantLib::ActualActual);
QuantLib::Date t = todaysDate()
std::vectorQuantLib::Time yearfracs;
std::transform(subsample.begin(),subsample.end(),
yearfracs.begin(),boost::bind(&QuantLib::ActualActual::yearFraction,&dc,t,_2))
Assuming you want each subsample item to be pass as t2 :
boost::bind (&QuantLib::ActualActual::yearFraction ,&dc ,t ,_1 , QuantLib::Date() , QuantLib::Date())
You need the _1, as you are generating a unary function object. IIRC, you need to specify the default args.
Also I assume yearFracs.size() >= subsamble.size()?
