~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() const
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)
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.
