Detailed Description

Initialize a new batched rank-dimensional FFT plan.

Assumes that the plan has been created already, and modifies the plan associated with the plan handle. The batch parameter tells hipFFT how many transforms to perform. Used in complicated usage case like flexible input and output layout.

Parameters

[in]	plan	Pointer to the FFT plan.
[in]	rank	Dimension of FFT transform (1, 2, or 3).
[in]	n	Number of elements in the x/y/z directions.
[in]	inembed
[in]	istride
[in]	idist	Distance between input batches.
[in]	onembed
[in]	ostride
[in]	odist	Distance between output batches.
[in]	type	FFT type.
[in]	batch	Number of batched transforms to perform.
[out]	workSize	Pointer to work area size (returned value).
