Function documentation

RooQuasiRandomGenerator(const RooQuasiRandomGenerator& )

 Perform one-time initialization of our static coefficient array if necessary
 and initialize our workspace.

~RooQuasiRandomGenerator()

void reset()

 Reset the workspace to its initial state.

Bool_t generate(UInt_t dimension, Double_t* vector)

 Generate the next number in the sequence for the specified dimension.
 The maximum dimension supported is 12.

void calculateCoefs(UInt_t dimension)

void calculateV(const int* px, int px_degree, int* pb, int* pb_degree, int* v, int maxv)

void polyMultiply(const int* pa, int pa_degree, const int* pb, int pb_degree, int* pc, int* pc_degree)

RooQuasiRandomGenerator(const RooQuasiRandomGenerator& )

Int_t add(Int_t x, Int_t y) const

 Z_2 field operations

{ return (x+y)%2; }

Int_t mul(Int_t x, Int_t y) const

{ return (x*y)%2; }

Int_t sub(Int_t x, Int_t y) const

{ return add(x,y); }
