Functions
double	IntensityDataFunctions::RelativeDifference (const SimulationResult &dat, const SimulationResult &ref)
	Returns sum of relative differences between each pair of elements: (a, b) -> 2*abs(a - b)/(a + b) ( and zero if a-b=0 ) More...
double	IntensityDataFunctions::getRelativeDifference (const OutputData< double > &dat, const OutputData< double > &ref)
	Returns relative difference between two data sets sum(dat[i] - ref[i])/ref[i]).
bool	IntensityDataFunctions::checkRelativeDifference (const OutputData< double > &dat, const OutputData< double > &ref, const double threshold)
	Returns true is relative difference is below threshold; prints informative output.
double	IntensityDataFunctions::getRelativeDifference (const IHistogram &dat, const IHistogram &ref)
double	IntensityDataFunctions::coordinateToBinf (double coordinate, const IAxis &axis)
	Transforms coordinate on axis into the bin-fraction-coordinate.
double	IntensityDataFunctions::coordinateFromBinf (double value, const IAxis &axis)
	Transforms bin-fraction-coordinate into axis coordinate.
void	IntensityDataFunctions::coordinateToBinf (double &x, double &y, const OutputData< double > &data)
	Transforms x,y coordinate from OutputData axes coordinates to bin-fraction-coordinates.
void	IntensityDataFunctions::coordinateFromBinf (double &x, double &y, const OutputData< double > &data)
	Transforms x,y coordinate from bin-fraction-coordinates to OutputData's axes coordinates.
std::vector< std::vector< double > >	IntensityDataFunctions::create2DArrayfromOutputData (const OutputData< double > &data)
	Creates a vector of vectors of double (2D Array) from OutputData.
std::vector< std::vector< double > >	IntensityDataFunctions::FT2DArray (const std::vector< std::vector< double >> &signal)
	Creates a Fourier Transform of a 2D Array (vector of vectors).
std::unique_ptr< OutputData< double > >	IntensityDataFunctions::createRelativeDifferenceData (const OutputData< double > &data, const OutputData< double > &reference)
std::unique_ptr< OutputData< double > >	IntensityDataFunctions::createRearrangedDataSet (const OutputData< double > &data, int n)
	Returns new object with input data rotated by n*90 deg counterclockwise (n > 0) or clockwise (n < 0) Axes are swapped if the data is effectively rotated by 90 or 270 degrees Applicable to 2D arrays only.
std::unique_ptr< OutputData< double > >	IntensityDataFunctions::createClippedDataSet (const OutputData< double > &origin, double x1, double y1, double x2, double y2)
	Returns new IntensityData objects which axes clipped to represent the specified rectangle.
std::unique_ptr< OutputData< double > >	IntensityDataFunctions::createOutputDatafrom2DArray (const std::vector< std::vector< double >> &array_2d)
	Creates OutputData from a 2D Array.
std::unique_ptr< OutputData< double > >	IntensityDataFunctions::createFFT (const OutputData< double > &data)
	Creates Fourier Transform (OutputData format) of intensity map (OutputData format).
