Executes a CUFFT real-to-complex (implicitly forward) transform plan
for double precision values.

cufftResult cufftExecD2Z( cufftHandle plan, cufftDoubleReal *idata, cufftDoubleComplex *odata );

CUFFT uses as input data the GPU memory pointed to by the idata
parameter. This function stores the non-redundant Fourier coefficients
in the odata array. If idata and odata are the same, this method does
an in-place transform (See CUFFT documentation for details on real
data FFTs.)

Input
----
plan      The cufftHandle object for the plan to update
idata     Pointer to the input data (in GPU memory) to transform
odata     Pointer to the output data (in GPU memory)
direction The transform direction: CUFFT_FORWARD or CUFFT_INVERSE

Output
----
odata Contains the complex Fourier coefficients

Return Values
----
CUFFT_SETUP_FAILED CUFFT library failed to initialize.
CUFFT_INVALID_PLAN The plan parameter is not a valid handle.
CUFFT_INVALID_VALUE The idata, odata, and/or direction parameter is not valid.
CUFFT_EXEC_FAILED CUFFT failed to execute the transform on GPU.
CUFFT_SUCCESS CUFFT successfully executed the FFT plan.
