template<typename T , typename FUNCTOR > T scythe::intsimp ( FUNCTOR  fun, T  a, T  b, unsigned int  N  ) Calculate the definite integral of a function from a to b. This function calculates the definite integral of a univariate function on the interval . Parameters: fun The function (or functor) whose definite integral is to be calculated. This function should both take and return a single argument of type T. a The starting value of the interval. b The ending value of the interval. N The number of subintervals to calculate. Increasing this number will improve the accuracy of the estimate but will also increase run-time. Exceptions: scythe_invalid_arg (Level 1) See also: adaptsimp(FUNCTOR fun, T a, T b, unsigned int& N, double tol = 1e-5) Note: Users will typically wish to implement fun in terms of a functor. Using a functor provides a generic way in which to evaluate functions with more than one parameter. Furthermore, although one can pass a function pointer to this routine, the compiler cannot inline and fully optimize code referenced by function pointers. References SCYTHE_CHECK_10.
