find a row in an array with largest value

[mshask]

Hi, I have this array:

0: OBB-9EF6FC (c7:6c:f0:9e:f6:fc) rssi:-53
1: OBB-602842 (c7:6c:f0:9e:f6:fc) rssi:-82
2: OBB-3H6FJ2 (c7:6c:f0:9e:f6:fc) rssi:-84
3: OBB-39DF41 (c7:6c:f0:9e:f6:fc) rssi:-81
4: OBB-494FOB (c7:6c:f0:9e:f6:fc) rssi:-82

And I need to find the row with the biggest rssi value, and have this row be an output. How do I do this?

Iterate through the array using auto-indexing tunnels.  Store the largest value and the index of that value in a shift register.  If you come across a larger value, then you update the shift registers.

How do I do this? I'm fairly new to labview.

Where are you stuck? Getting the numbers, or getting the maximum?

If it's both, it might be time for some of the (free) courses...

I'm making a lot of assumption in this solution. Assuming the string before the number is always the same length, and that the - is part of the number. (if its not you just need to change the offset).

But two useful nodes to look at are Array Max & Min, and Decimal String To Number. Both of those basically extract all the data without you doing any work.

You could just use Match Pattern to look for "rssi:" and use the After Substring to convert to a number.

Or use a good old Scan From String, with "%d: OBB-%6x (%2x:%2x:%2x:%2x:%2x:%2x) rssi:%d" as scan string. Or "%d: OBB-%6x (%[^)]) rssi:%d"  You'd get an integer as a result.

Or a regular expression with "rssi:(.*)$", and then use the first capturing group.

Above Snippet will hold the String Data Array of the respective numeric Value and the Last Element will hold the biggest rssi value.

Hope this helps!

Hi Palanive,

you should make that "NumericRange" element the first element in the cluster!

(Using AutoCleanup would help, too.)

(I removed the minus char from the search expression as I guess it is part of the dB value…)

GerdW,

Thanks for the update!
