Hi, I'm currently facing a problem in LabVIEW array manipulation. I'm using LabVIEW Vision VI called "IMAQ Count objects". It's extracting me the XY of each objects at each frames. However, it doesn't track object frames by frame but simply "randomly" extract XY of each object on the frame. This is why I would like to be able from row to row, to order every time each point by the previous closer one. As it's not really easy to understand and my english level isn't good enough, here is an example done in excel : Also,it's not simply "order every number" by ascending order, but it's XY coordinates. I've also created a VI, in which I'm able to get : - Difference between each X and Y at each frame - From that, the distance between the 2 points - Then order it by ascending order. Maybe it can help ? So, I've attached my VIs. Start OrderXYbyClosest.vi and put Distance2Points.vi in the same folder. Please, don't say me it's a "Vision" problem, it's just array manipulation here that I want to do, not request a Vision feature 🙂 Thank you very much, Sébastien

Sort XY by closest

Last time I checked (very long ago), taking the absolute value instead of "complex to polar" (while ignoring the angle output), is slightly more efficient. Same result. 😄
