RooAdaptiveGaussKronrodIntegrator1D Class Reference

RooAdaptiveGaussKronrodIntegrator1D implements the Gauss-Kronrod integration algorithm.

An adaptive Gaussian quadrature method for numerical integration in which error is estimated based on evaluation at special points known as the "Kronrod points". By suitably picking these points, abscissas from previous iterations can be reused as part of the new set of points, whereas usual Gaussian quadrature would require recomputation of all abscissas at each iteration.

This class automatically handles (-inf,+inf) integrals by dividing the integration in three regions (-inf,-1), (-1,1), (1,inf) and calculating the 1st and 3rd term using a \( x \rightarrow 1/x \) coordinate transformation.

This class embeds the adaptive Gauss-Kronrod integrator from the GNU Scientific Library version 1.5 and applies a chosen rule ( 10-, 21-, 31-, 41, 51- or 61-point). The integration domain is subdivided and recursively integrated until the required precision is reached.

For integrands with integrable singularities the Wynn epsilon rule can be selected to speed up the convergence of these integrals.
