bool npstat::closeWithinTolerance ( const double &  a, const double &  b, const double &  tol  )

inline

Check if two doubles are within certain relative tolerance from each other. The "tol" argument which specifies the tolerance must be non-negative.

template<typename Histo >

void npstat::convertHistoToDensity	(	Histo *	histogram,
		bool	knownNonNegative = false
	)

Reset negative histogram bins to zero and then divide histogram bin contents by the histogram integral. If the "knownNonNegative" argument is true, it will be assumed that there are no negative bins, and their explicit reset is unnecessary.

This function will throw npstat::NpstatRuntimeError in case the histogram is empty after all negative bins are reset.

This function is not a member of the HistoND class itself because these operations do not necessarily make sense for all bin types. Making such operation a member would make creation of HistoND scripting API (e.g., for python) more difficult.

The conversion from non-uniform grid axis to non-uniform histogram axis is only unambiguous when some additional info is available. Here, in particular, we are asking for the position of the axis minimum. This function will throw npstat::NpstatInvalidArgument in case the conversion is impossible.

Generate a density scanning map for subsequent use with the "DensityScanND" template when a density is to be convolved with the histogram data. Only histograms with uniform binning can be used here.

The "doubleDataRange" should be set "true" in case the data will be mirrored (or just empty range added) to avoid circular spilling after convolution.

Get the coefficients of the interpolating polynomial. The interpolated function values are provided at 0, 1, ... The return value of the function is the number of coefficients (i.e., the polynomial degree plus one). On exit, the coefficients are placed into the "buffer" array in the order of increasing monomial degree. The length of the provided buffer must be sufficient to hold all these coefficients.

A utility for filling one array using values of another. The array shapes do not have to be the same but the ranks have to be. Roughly, the arrays are treated as values of histogram bins inside the unit box. The array "to" is filled either with the closest bin value of the array "from" or with an interpolated value (if "interpolationDegree" parameter is not 0).

interpolationDegree parameter must be one of 0, 1, or 3.
