Re: [Boost-users] [accumulators] Compilation Problem

OK, thanks. I finaly wrote this : accumulator_settag::density > angular_acc(tag::density::num_bins = Constantes::_pi/16.,tag::density::cache_size = 2.*Constantes::_pi); int nb_ech = (int)( (itb->norme()) / pas ); TPoint2D <double> direction = itb->p1 - itb->p2; direction.normaliser(); // On parcourt tous les échantillons for (unsigned int j=0;jp1 + direction * j; double angle = atan2( gy(pt) , gx(pt) ); angular_acc(angle); } Now that I am here, how can I extract the histogram ?

Hi all,

I am trying to use boost::accumulators lib and I would appreciate some help. I do not know how to use the tag::density. How do I use :

accumulator_set angular_acc;

Have a look at the docs: http://boost-sandbox.sourceforge.net/libs/accumulators/doc/html/index.html

That should be:

accumulator_settag::density > angular_acc;

...

and set

density::cache_size density::num_bins

To have for example 10 subdivisions between -pi and pi ? Then, how do I extract the results of the accumulation ?

The docs tell you all this, too.
