ippsFFTwd_CToC_64fc_I only updates on first call

Hi,

I am using FFT calculation in my app. when calling ippsFFTwd_CToC_64fc_I the buffer values updates only on the first iteration call.

From second iteration, the buffer values are always the same as the values I've received on the first iteration.

what could be the cause of that?

thanks,

Gil

Hi Volovich,

I did not see any problem you described, I could not reproduce, please check if you are using the API for In-place operation. And provide a reproducer. Thanks.

Best regards,
Fiona
