Add or delete from array base on a condition

[tintin_99]

Hi

I would like to add an element to an array if a condition is true.

For example in the attached picture, I would like to add one entry to array when the first element is yes, but I would like to add nothing if the first element is not yes

could you please let me know what should I add to false structure to not add any entry to array. I see if I use defualt value or defualt constant it still adds 0,0 to array

do you have LV2013?

If so, you can use the new conditional tunnel output:

This is present in 2012 also.

The conditional indexing came out with LabVIEW 2012.  That is the easy way.  If you are using older, then you need to use a shift register to hold your growing array with a Build Array inside of a case structure.

Move that equals outside the loop (the optimizer probably does it anyway but, we should point out equals works with arrays)
