    Description

      The following code:

      final UnivariateFunction f = PolynomialsUtils.createHermitePolynomial(deg);
final double integ = new SimpsonIntegrator(9, 50).integrate(1100, f, 0, 0.5);

      terminates as expected, while this one

      final UnivariateFunction f = PolynomialsUtils.createHermitePolynomial(deg);
final double integ = new SimpsonIntegrator(10, 50).integrate(1100, f, 0, 0.5);

      raises an exception:

      TooManyEvaluationsException: illegal state: maximal count (1,100) exceeded: evaluations

          relates to

          Bug - A problem which impairs or prevents the functions of the product. MATH-1458 Simpson Integrator computes incorrect value at minimum iterations=1 and wastes an iteration

          • Minor - Minor loss of function, or other problem where easy workaround is present.
