Need help outputting array

[kitoskeris4]

hello, I am completely new to labVIEW. We just started learning simple functions in class. One exercise is to output an 3x3 array of : 2, 4, 6 8, 10, 12 14, 16, 18 It must be done specifically by using nested for loop and formula node, and actually logically computed instead of just storing the inputs. I am able to output a 3x3 but can’t figure out formula or what to do with formula node for desired output values. Any help appreciated, thanks!!

Hello kitoskeris4,

I Guess this is a home work application, Just try the basics and Share the one which you have tried to reach the solution, so that others can guide you to reach the final output.

The top of the forum has many links to training resources. Once you completed them and there are remaining questions, please ask more specific questions. I assume the topic has also been covered in class. Have a look at your class notes.

What schools is this and what kind of qualifications does your teacher have? Asking to use a "formula node" is highly unusual. You don't need nested FOR loops, you can reshape at the end. Also the term "logically computed" is a bit weird. Logic typically involves booleans, not numerics, but it can be colloquially used for both.

As I said, nested FOR loops and formula nodes are not needed, but since you have these unreasonable requirements, the following is not a valid solution. Still, it might give you some ideas.... 🙂 Try to recreate it from scratch.

For the most generic case, your formula node is in the innermost loop and needs five inputs wired to it to produce one output element

1. The size of the dimension (3 in your case)
2. The iteration count (from the [i] terminal) of the outer FOR loop.
3. The iteration could of the inner FOR loop.
4. The step size between elements (2 in your case)
5. The offset, i.e. the value of the first element (2 in your case).

This is very simple math. Try to solve it with paper&pencil first.
