MKL DFT descriptor generation question

Hi there,

I have a question about the DFTI descriptor.

So the problem is 1Kx1K complex number, row major.  for each row of 1K element, I would like to compute size-16 FFT with stride 64. That is - I do not want to compute size -1024 FFT but only size-16 FFT.

For example: these 16- elements are element 0, 64, 128, 192, ... 1008. and another size-16 FFT elements are element 1, 65, 129, ... 1009, etc.

And the same computation is applied on all the 1K rows.

I had a look at the reference manual but am not sure if the descriptor could generate that.

specifically, I don't know arguments like:

1) num_of_transforms 2) stride, 3) dist.

Thanks!
