[Pyublas] Calling norm_2 on numpy_strided_vector

[Neal Becker]

template<typename out_t, typename in_t>
inline out_t norm_2 (in_t const& in) {
return ublas::norm_2 (in);
}

[with out_t = double,
in_t = pyublas::numpy_strided_vector<std::complex<double> >]

Gives:
/usr/local/src/boost.hg/boost/numeric/ublas/vector_expression.hpp:1447: error:
no matching function for call to
'boost::numeric::ublas::vector_scalar_unary<boost::numeric::ublas::vector_slice<pyublas::numpy_vector<std::complex<double>

, F =

boost::numeric::ublas::vector_norm_2<boost::numeric::ublas::vector_slice<pyublas::numpy_vector<std::complex<double>

]

.... more candidates....

Any ideas? Can't I use pyublas::numpy_strided_vector<T> anywhere
ublas::vector could be used? (I'm assuming the answer is the same if it was
pyublas::numpy_vector<T>)
