The functions f1 and f2 are interpolating functions and the domain of the integral is the domain of interpolating function f1. It uses Gaussian quadrature of order n for each interval between the knots of the interpolating function f1. ### ### ===== Input ===== ===== Input ===== - * bla : Integer + * q : real - * bla2 : Real + * k : integer + * f1: InterpolatingFunction + * f2: InterpolatingFunction + * n : unsigned int - optional, default is 3, maximum is 7 ===== Output ===== ===== Output ===== - * bla : real + * real ===== Example ===== ===== Example =====
