double my_f (double x, void *p)
 
double integrate (const double &a, const double &s0, const double &lambdaleft, const double &lambdaright, const int &n)
 

Detailed Description


Integrate performs a contour integral to find the nth derivative of the
Tanh model fringe function. It uses Cauchy's integral formula to do so.
