type(c_ptr) function	fftw_plan_dft_ (rank, n, in, out, sign, flags)

Detailed Description

Creates a basic plan for a multidimensional, double-precision, complex discrete Fourier transform of lengths n[0] x n[1] x ... x n[rank-1].

Parameters

[in]	rank	- strictly positive rank of the transform;
[in]	n	- array of strictly positive lengths of the transform (must be of size rank);
[in]	in	- pointer to the input buffer for the transform;
[in]	out	- pointer to the output buffer for the transform;
[in]	sign	- exponent sign defining the desired complex transform (FFTW_FORWARD or FFTW_BACKWARD );
[in]	flags	- bitwise OR (|) combination of zero or more constant flag values.

Returns

a valid double-precision hipFFTW plan ready for execution upon success (nullptr otherwise).
