Construct a THnBase with "dim" dimensions, "nbins" holds the number of bins for each dimension; "xmin" and "xmax" the minimal and maximal value for each dimension.
The arrays "xmin" and "xmax" can be NULL; in that case SetBinEdges() must be called for each dimension.

Fit a THnSparse with function f.
since the data is sparse by default a likelihood fit is performed merging all the regions with empty bins for betetr performance efficiency
Since the THnSparse is not drawn no graphics options are passed Here is the list of possible options
= "I" Use integral of function in bin instead of value at bin center
= "X" Use chi2 method (default is log-likelihood method)
= "U" Use a User specified fitting algorithm (via SetFCN)
= "Q" Quiet mode (minimum printing)
= "V" Verbose mode (default is between Q and V)
= "E" Perform better Errors estimation using Minos technique
= "B" Use this option when you want to fix one or more parameters
and the fitting function is like "gaus", "expo", "poln", "landau".
= "M" More. Improve fit results
= "R" Use the Range specified in the function range

Generate an n-dimensional random tuple based on the histogrammed distribution.
If subBinRandom, the returned tuple will be additionally randomly distributed within the randomized bin, using a flat distribution.

Multiply this histogram by histogram h this = this * h Note that if h has Sumw2 set, Sumw2 is automatically called for this if not already set.

Performs the operation: this = this*c*f1 if errors are defined, errors are also recalculated.
Only bins inside the function range are recomputed. IMPORTANT NOTE: If you intend to use the errors of this histogram later you should call Sumw2 before making this operation. This is particularly important if you fit the histogram after calling Multiply()

Print a THnBase.
If "option" contains: 'a': print axis details 'm': print memory usage 's': print statistics 'c': print its content, too (this can generate a LOT of output!) Other options are forwarded to PrintEntries().
Reimplemented from TNamed.

Print one bin.
If "idx" is != -1 use that to determine the bin, otherwise (if "idx" == -1) use the coordinate in "bin". If "options" contains: '0': only print bins with an error or content != 0 Return whether the bin was printed (depends on options)

Print "howmany" entries starting at "from".

Project all bins into a ndim-dimensional THn / THnSparse (whatever *this is) or if (ndim < 4 and !wantNDim) a TH1/2/3 histogram, keeping only axes in dim (specifying ndim dimensions).
If "option" contains "E" errors will be calculated. "A" ranges of the taget axes will be ignored. "O" original axis range of the taget axes will be kept, but only bins inside the selected range will be filled.

Add contents of h scaled by c to this histogram: this = this + c * h Note that if h has Sumw2 set, Sumw2 is automatically called for this if not already set.
In contrast to Add(), RebinnedAdd() does not require consistent binning of this and h; instead, each bin's center is used to determine the target bin.

Change (i.e.
set) the title.
If title is in the form "stringt;string0;string1;string2 ..." the histogram title is set to stringt, the title of axis0 to string0, of axis1 to string1, of axis2 to string2, etc, just like it is done for TH1/TH2/TH3. To insert the character ";" in one of the titles, one should use "#;" or "#semicolon".
