[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
