Arrays

[Tycho]

Hi, I have an array 3x1, and I want to see if it has two elements equal,
three elements equal, or all elements different. More, I'd like to see
which elements are equal (for example, I have [1,3,3], and I want to see
if the elements equal are 1s, 2s or 3s, in my example are 3s).
How can I do?
Thanks

Here is a simple example just using some loops and array functions to do what you are looking for. I did not attach the actual code because I use 7.0 and you probably dont have that, so you can recreate the vi from the image, it will do what you want.

Hope this helps!

On a side note, you will need a more complicated architecture than that if you are planning on doing this with an array of more than three. However, for three elements, this works fine, because you can never have more than one number repeating.

Here's a simple solution that would not scale well for array with millions of elements. 😉

Sorry for the misspellings of frequent. Since I am left-handed, the left fingers are sometimes a few nanoseconds faster than the right hand while typing, leading to race conditions. 😄

jrpe: 99% of user here use version newer than 7.0, so almost everybody should be able to open your VIs. It is more tricky in my case, because I am using 8.5. Only a small percentage can open these at the moment. Saving for previous adds extra work because I still would not post them without validating in the earlier version first.

I assumed that you have a 1D array with 3 elements. If your input is actually a 3x1 2D array, things need to be modified slightly, of course. 🙂
