boost::histogram::algorithm::reduce — Shrink, slice, and/or rebin axes of a histogram.
// In header: <boost/histogram/algorithm/reduce.hpp> template<typename Histogram, class... Ts> Histogram reduce(const Histogram & hist, const reduce_command & opt, const Ts &... opts);
Returns a new reduced histogram and leaves the original histogram untouched.
The commands rebin
andshrink
orslice
for the same axis are automatically combined, this is not an error. Passing ashrink
and aslice
command for the same axis or tworebin
commands triggers an invalid_argument exception. It is safe to reduce histograms with some axis that are not reducible along the other axes. Trying to reducing a non-reducible axis triggers an invalid_argument exception.
An overload allows one to pass an iterable of reduce_command.
