LabVIEW
Pulling single element from 2D array
Here is some useful tips for the Labview beginner (we have all been there some time)
1)Then starting a new Labview session enable context help (Ctrl+h). Do not be afraid to use the detailed help option
2)Then stuck, go to help in the toolbar then select find examples
3) Before you post in this forum always do 1) and 2). That is mandatory
The link above gives a confusing solution that is only partially correct.
You simply use "Index array", no resizing needed. (you cannot change the number of inputs, just the number of outputs!). You will get one index terminal for each dimension of the array per element you want and you only want one element. No resizing needed! 😉
I am not sure what you mean by "store in a numeric DBL". The data is in the wire coming out of the "index array" node and you can re-use it in downstream code or also hook up an numeric indicator if it is of interest to the operator. If you want to use it in later iterations, keep it in a feedback node. You can also place it in a queue or shared variable, depending on the requirements. Can you tell us a little more what you want to do?
I am also not sure what you mean by "2D array of decimal numbers". "Decimal" is just a cosmetic feature of a control or indicator. Is is a 2D array of numerics? Is it a 2D array of decimal formatted strings? If you have a string, you need to scan it. If you have a different numeric data type, you can convert it to DBL.
