is an option to NewtonCotesWeights and NewtonCotesError that specifies whether the endpoints are to be included as abscissas.


  • To use , you first need to load the Numerical Differential Equation Analysis Package using Needs["NumericalDifferentialEquationAnalysis`"].
  • Valid settings are and .
  • With the default setting , the endpoints are included as abscissas.
  • With the setting , the endpoints are not included as abscissas. In this case, the initial abscissa is chosen to be a half step above the lower endpoint.
