cummulative sum elements in array(one by one)

[Ericleong]

Dear All:

         I have a big problem that I want the elements in array cummulative sum one by one, such that I want the original array

 A = [5,7,11,15,16], after operation, it will get another array B = [5,12,23,38,54]! Can anyone help me? Thanks for your help!

This is actually really simple and would be a good excercise in learning LabVIEW fundamentals. You can use a for loop with a shift register and an add function. If you need help in learning LabVIEW, you should check out the resources at http://www.ni.com/devzone/lvzone/fundamentals.htm.

Try to write something and if you get stuck, post the code you have written. I think that's the best way to learn and not just be handed an answer.

I am so sorry that I also can't find out the correct way to create the array what I wanted  through using "for loop",

please help me to solve the problem.

Thanks a lot!

Why don't you attach a picture of what you have tried? I suspect that this is a homework problem and I don't think you will learn much if you are just given the answer.

Dear Dennis Kn…

Thank you every much, I just found the way to solve the problem, this is not homework, this is my project (final year), anyway, thank you for your teaching....

It is 11 years after the question.

Hi student,

why don't you use an autoindexing output tunnel?

@Gerd - it is a subset of something else.  Basically, you are right and that is a better way to go.
