As stated in my title slide Stephen Loftus-Mercer's original Malleable VIs presentation is available on the LabVIEW NI Week 2019 wiki page, along with the video of the presentation linked on YouTube. Stephen was gracious and let me present his information this evening.
Search the page for Malleable and it will take you to the links.
I should have included the most likely to be used Malleable VIs on a slide the other night.
Looking around the palette for the new Array VIMs there is the Remove Duplicates from 1D array VIM that along with Stall Data Flow.vim and Is Value Changed.vim will probably be used often.
So far my top uses of VIM are a simple custom one I wrote buried in one of my classes that replaced a bunch of polymorphic instances that dealt with converting data, and definitely the Is Value Changed and Stall Data.vim ones.
I'd be interested in seeing others post over time if they have started using them and what their top VIM are.
Of course, if you use Variant Attributes and move to LV2019 you'll probably get used to using Sets and Maps which are all Malleable VIs. I'll be looking hard at those now that I have started using Malleable VIs since I leverage Variant LUT very often.
I believe I mentioned that there was a problem with the 2019 shipping code example VIs that I found. If I didn't be aware that Stephen Loftus-Mercer has provided updated Malleable VIs for the Vi.lib/Array
See the following discussion and posted corrected VIs.
I have been using my own Malleable VIs with no issues thus far.
