Function documentation

void registerIntegrator(RooNumIntFactory& fact)
RooIntegrator1D(const RooIntegrator1D& )
RooIntegrator1D(const RooAbsFunc& function, SummationRule rule, Int_t maxSteps, Double_t eps)
 Use this form of the constructor to integrate over the function's default range.
RooIntegrator1D(const RooAbsFunc& function, Double_t xmin, Double_t xmax, RooIntegrator1D::SummationRule rule = Trapezoid, Int_t maxSteps = 0, Double_t eps = 0)
 Use this form of the constructor to override the function's default range.
RooIntegrator1D(const RooAbsFunc& function, const RooNumIntConfig& config)
 Use this form of the constructor to integrate over the function's default range.
RooIntegrator1D(const RooAbsFunc& function, Double_t xmin, Double_t xmax, const RooNumIntConfig& config)
 Use this form of the constructor to override the function's default range.
RooAbsIntegrator* clone(const RooAbsFunc& function, const RooNumIntConfig& config) const
Bool_t initialize()
 apply defaults if necessary
~RooIntegrator1D()
 Release integrator workspace
Bool_t setLimits(Double_t xmin, Double_t xmax)
 Change our integration limits. Return kTRUE if the new limits are
 ok, or otherwise kFALSE. Always returns kFALSE and does nothing
 if this object was constructed to always use our integrand's limits.
Bool_t checkLimits()
 Check that our integration range is finite and otherwise return kFALSE.
 Update the limits from the integrand if requested.
Double_t integral(const Double_t* yvec = 0)
Double_t addMidpoints(Int_t n)
 Calculate the n-th stage of refinement of the Second Euler-Maclaurin
 summation rule which has the useful property of not evaluating the
 integrand at either of its endpoints but requires more function
 evaluations than the trapezoidal rule. This rule can be used with
 a suitable change of variables to estimate improper integrals.
Double_t addTrapezoids(Int_t n)
 Calculate the n-th stage of refinement of the extended trapezoidal
 summation rule. This is the most efficient rule for a well behaved
 integrand that can be evaluated over its entire range, including the
 endpoints.
void extrapolate(Int_t n)
RooIntegrator1D(const RooIntegrator1D& )
Bool_t setUseIntegrandLimits(Bool_t flag)
{_useIntegrandLimits = flag ; return kTRUE ; }
Bool_t canIntegrate1D()
{ return kTRUE ; }
Bool_t canIntegrate2D()
{ return kFALSE ; }
Bool_t canIntegrateND()
{ return kFALSE ; }
Bool_t canIntegrateOpenEnded()
{ return kFALSE ; }
Double_t* xvec(Double_t& xx)
{ _x[0] = xx ; return _x ; }
