gives the leading term in the error of the elementary n-point Gaussian quadrature formula for the function f on an interval from a to b.
attempts to give a result with prec digits of precision.
- To use , you first need to load the Numerical Differential Equation Analysis Package using Needs["NumericalDifferentialEquationAnalysis`"].
- The function f may be a pure function or a named function defined using Set or SetDelayed.
- The error is given as a function of n, a, and b multiplied by an derivative of the function f. The size of the error is bounded by the maximum of this expression over the interval from a to b.
