Class Description

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()

Int_t add(Int_t x, Int_t y)

 Z_2 field operations

{ return (x+y)%2; }

Int_t mul(Int_t x, Int_t y)

{ return (x*y)%2; }

Int_t sub(Int_t x, Int_t y)

{ return add(x,y); }
