typedef accumulator_set<double, stats<boost::accumulators::tag::tail_quantile<left> > > accumulator_t_left;

typedef accumulator_set<double, stats<boost::accumulators::tag::tail_quantile<right> > > accumulator_t_right;

accumulator_t_right acc0( boost::accumulators::tag::tail<right>::cache_size = c );

{

// here push your data in to acc0

acc0(r);

}

get the quantile or whatever:

double tqueryP=quantile(acc0, quantile_probability = 0.50 );

cheers Arman.

Maybe a better explanation is I want a c++ function that will do what
the Matlab hist() function does:
