Partial sum/adjacent difference with IPP

overspawn — Sat, 29 May 2004 01:37:45 GMT

Is there a way to compute partial sums or adjacent differences with IPP?

Partial sum is:

DST[0]= SRC[0]
DST= SRC+DST[i-1] for i > 0

Adjacent difference is (roughly) reverse operation:
DST = SRC-SRC[i-1]

Hi,

No, we do not provide such operations, at least for now. So,you can submityour requeston Premier service. By the way, where do you think they would be useful?

I use partial_sum to compute vertex positions along polygon's perimeter based on known edge lengths.
These functions are part of C++ STL so I guess there is a lot of other applications.
