Hi Steve,
I think this might be due to the fact that the Adaptive Filter Toolkit, of which 2013 is the latest edition, is only available for LabVIEW.
To implement what you see in LabVIEW examples in CVI you will likely have to work on emulating the toolkit's functions for CVI first, then you should be able to apply the same general logic with those functions.
I would recommend making a new forum post, since this one is old and will have a low visibility, with a more specific question. Then you will likely obtain a more useful response from others in the forum.
