[Boost-users] Using boost modified bessel functions with complex arguments

Dear all, Does anyone know how to call boost's modified bessel function of the first kind using a complex argument? Specifically I want the positive half integer order with complex argument so I use: #include <boost/math/special_functions/bessel.hpp> std::complex<double> output = boost::math::cyl_bessel_i(double nhalf, std::complex<double> x); but this gives me a huge list of compiler errors which seems to suggest the std::complex<double> template isn't valid. I am able to call other boost math library functions so I don't believe my install is to blame here. Thanks for any help Ross
