integrate method

@override ({List<double> guesses, double result}) integrate()

Calculates the numerical value of the definite function integral between lowerBound and upperBound. Returns a Record object whose members are:

• a guesses named field, which contains the list of values generated by the algorithm on each step;

• a result named field, which contains the evaluation of the integral in the [a, b] interval.

Implementation

@override
({List<double> guesses, double result}) integrate() {
  final guesses = <double>[];
  final result = _adaptive(lowerBound, upperBound, guesses);

  return (
    guesses: guesses,
    result: result,
  );
}
