Hello,

I have a ragged array with multiple shaped 1D sequences

I am looking to make a batched 1D FFT on two 1D sequence that are contiguous but not adjacent.

```
int rank = 1; // 1D FFT
int batch_size = 2; // Number of rings to transform
int n[] = {size}; // Size of each FFT
int *inembed = NULL; // Stride of input data
int istride = 1; // Distance between consecutive elements in the same batch
int idist = 188; // Distance between the starting points of two consecutive batches
int *onembed = NULL; // Stride of output data
int ostride = 1; // Distance between consecutive elements in the same batch
int odist = 188;
std::cout << "For ring " << i << " size is " << size << " dist is " << dist << std::endl;
CUFFT_CALL(cufftMakePlanMany(plan, rank, n, inembed, istride, idist, onembed, ostride, odist,
CUFFT_C2C, batch_size, &polar_worksize));
```

The size if 4 and the idist = odist is 188

Yet when I execute the plan, the first 8 elements are transformed, instead of the first 4 and the last 4 of my array.

Anyone have an idea how can I use this from the documentation :

```
1D
input[ b * idist + x * istride ]
output[ b * odist + x * ostride ]
```

Thank you
