I tried to use the 'mode' vi under LabVIEW6.1 to get the mode of an array. But the result obviously wrong. It returned a number that never appeared in the array. And the vi ask me to provide interval, but how can an array of numbers has an interval? Who can tell me how can I get the mode correctly? My array is attached with this question. I'm working on my thesis, the problem is urgent to me. Thanks!
