display every 5th element of the array

[M Boat]

Hello,

I am trying to take a for loop iteration and pull out every 5th element of data. This will eventually go to comparison of some type to activate a true/false case structure.

What I am having difficulty with is getting the algorithm down. I have attached a simple for loop that has a constant of 100 attached to the "N" terminal with a random number generator multiplied by 100, sending that through the for loop to give an array on the other side.

I will continue to rack my brain to see if I can solve this, but I have spent the better part of the morning trying to figure, and search this out, and have come up with nothing.

See attached vi.

Decimate array resized for five outputs?

You can use a couple of different methods to do this.  Have a look at the Decimate 1D Array and Quotient & Remainder functions.  I have attached a modifed version of your code.

Here is the code

Maybe I was confusing in the initial post.

I am trying to use the iteration of the for loop to pull out every 5th element of the array. I am not even sure how to use the decimate array function.

Have you looked at my modified code?

yes, it seems to work. 🙂 I am working on some indexing issues of where it starts in my data. I will post up a screen shot here shortly.

Can you use this method. It was that Ben suggested I think

Maybe something like this?

Here are some images of my code that your solution went into. I would just post the vi's, but my project has a gazillion vi's to it to run, and I am limited to 3 attachments. See below.

Like I said, it seems to be working but, I am having some indexing issues. Also, the lines that start out with "0.000" are supposed to be blank. Basically everywhere there is 0.000, I am trying to make go away. The data I need to be there is every multiple of 5, ie: 5,10, 15, 20, etc.. until it gets to the end of the data file.
