Would there be any interest in a fast fourier transformation class?
I've written one that has the following signature:
template<class DOUBLE,
class COMPLEX = std::complex<DOUBLE>,
class VECTOR = std::vector<COMPLEX> >
class fft
{
static inline void transform(VECTOR&, bool);
};
The bool parameter on the transform specifies whether we're taking
the inverse or not, and defaults to false.
The reason for the class (as distinct from a templated function) is
to enable default template arguments -
there's no actual state.
If there's interest, I'll tidy things up (appropriate copyright etc)
and upload it for initial review.
