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
