	Checks the status of a cufft command and in case of a failure, converts it to a C++ exception.
template<typename precision_type , typename index >
void	convert (cudaStream_t stream, index num_entries, precision_type const source[], std::complex< precision_type > destination[])
	Convert real numbers to complex when both are located on the GPU device. More...
template<typename precision_type , typename index >
void	convert (cudaStream_t stream, index num_entries, std::complex< precision_type > const source[], precision_type destination[])
	Convert complex numbers to real when both are located on the GPU device. More...
