It would be a timesaver to have a Search 1D Array In Reverse! Obviously we can code this ourselves, but a LabVIEW function would make it handier (and hopefully faster).
You should be able to do a reverse 1-D array then do a search on that. If I remember correctly what I read in other posts, that reversing a 1-D array doesn't cost you anything in terms of time or memory, that LabVIEW just knows to index the array from the opposite end.
Yes, that's what I usually do. But then you have to subtract the result from the size of the array and adjust the index accordingly, plus do the error checking to trap the condition that the element was not found, so if NI would do that for us, we'd have to think less (and it would take less space on the diagram), or if we made a VI to do it, it would be one less VI we'd have to keep track of.
I shouldn't have used the word "error". What I mean is that if there's no element found, you would still want to return -1 (like the normal Search 1D Array).
Yes, but if you put in arithmetic after the fact to correct for the reversal (i.e. array size minus the search output) then it's no longer -1. My point is that it's a minor nuisance to write the code, or maintain the VI that does the reverse search.
And although the reverse array does not really reverse the data, it will create a copy of the data when the original and the reversed array are needed after the reverse. So it might cost memory and CPU. I think?
