Title: Implementation of the Bin Hierarchy Method for restoring a smooth function from a sampled histogram,
Abstract: We present $\texttt{BHM}$, a tool for restoring a smooth function from a
sampled histogram using the bin hierarchy method. The theoretical background of
the method is presented in [arXiv:1707.07625]. The code automatically generates
a smooth polynomial spline with the minimal acceptable number of knots from the
input data. It works universally for any sufficiently regular shaped
distribution and any level of data quality, requiring almost no external
parameter specification. It is particularly useful for large-scale numerical
data analysis. This paper explains the details of the implementation and the
use of the program.
