fftw_cleanup()

template<typename realT >

void mx::math::ft::fftw_cleanup

(

)

Cleanup persistent planner data.

fftw_make_planner_thread_safe()

template<typename realT >

void mx::math::ft::fftw_make_planner_thread_safe

(

)

Wrapper for fftwX_make_planner_thread_safe()

Template Parameters

realT

the real floating point type

fftw_plan_dft()

template<typename inputDataT , typename outputDataT >

fftwTypeSpec< inputDataT, outputDataT >::planT mx::math::ft::fftw_plan_dft	(	std::vector< int >	n,
		inputDataT *	in,
		outputDataT *	out,
		int	sign,
		unsigned	flags
	)

Wrapper for the fftwX_plan_dft functions.

Parameters

n	is a vector of ints containing the size of each dimension.
in	is the input data array
out	is the output data array
sign	specifies forward or backwards, i.e. FFTW_FORWARD or FFTW_BACKWARD.
flags	other fftw flags

Returns

an fftw plan for the types specified.

Template Parameters

inputDataT	the data type of the input array
outputDataT	the data type of the output array

fftw_plan_with_nthreads()

template<typename realT >

void mx::math::ft::fftw_plan_with_nthreads

(

int

nthreads

)

Tell the FFTW planner how many threads to use.

Template Parameters

realT

the real floating point type.

Parameters

[in]

nthreads

the number of threads. Set to 1 to disable threads.
