Function documentation

AliCorrectionMatrix()

 default constructor

AliCorrectionMatrix(const Char_t* name, const Char_t* title)

 constructor initializing tnamed

AliCorrectionMatrix(const AliCorrectionMatrix& c)

 copy constructor

AliCorrectionMatrix & operator=(const AliCorrectionMatrix& corrMatrix)

 assigment operator

void Copy(TObject& c) const

 copy function

void SetAxisTitles(const Char_t* titleX = "", const Char_t* titleY = "", const Char_t* titleZ = "")

 method for setting the axis titles of the histograms

Long64_t Merge(TCollection* list)

 Merge a list of AliCorrectionMatrix objects with this (needed for
 PROOF).
 Returns the number of merged objects (including this).

void Divide()

 divides generated by measured to get the correction

void Multiply()

 multiplies measured with correction to get the generated

void Add(AliCorrectionMatrix* aMatrixToAdd, Float_t c = 1)

 adds the measured and generated of aMatrixToAdd to measured and generated of this

 NB: the correction will naturally stay the same

Bool_t LoadHistograms(const Char_t* dir = 0)

 loads the histograms from a file
 if dir is empty a directory with the name of this object is taken (like in SaveHistogram)

void SaveHistograms()

 saves the histograms

void DrawHistograms(const Char_t* canvasName = 0)

 draws all histograms on one TCanvas
 if canvasName is 0 the name of this object is taken

void ReduceInformation()

 this function deletes the measured and generated histograms to reduce the amount of data
 in memory

void Reset(Option_t* option = "")

 resets the histograms

void SetCorrectionToUnity()

 sets the correction matrix to unity

void Scale(Double_t factor)

 scales the generated and measured histogram with the given factor

void ResetErrorsOnCorrections()

 set the errors on the correction matrix to 0

TH1* GetGeneratedHistogram()

{ return fhGene; }

TH1* GetMeasuredHistogram()

{ return fhMeas; }

TH1* GetCorrectionHistogram()

{ return fhCorr; }

void SetGeneratedHistogram(TH1* agene)

{ fhGene = agene; }

void SetMeasuredHistogram(TH1* ameas)

{ fhMeas = ameas; }

void SetCorrectionHistogram(TH1* acorr)

{ fhCorr = acorr; }
