Extrapolation quadrature from equispaced samples of functions with jumps

HIGHLIGHTS

  • who: Jean-Paul Berrut from the Du00e9partement de Mathu00e9matiques, Universitu00e9 de Fribourg, Pu00e9rolles, Fribourg, Switzerland have published the Article: Extrapolation quadrature from equispaced samples of functions with jumps, in the Journal: (JOURNAL)
  • what: The authors develop an method based on this extended for the of such discontinuous functions.

SUMMARY

    In the exceptional case where the values of the derivatives are known on both sides of the jumps, substituting them into easily permits the improvement of the Riemann values (see ). The number of trapezoidal values necessary for an extrapolation is not always . . .
