Split 2d array where the maximum value

[AymanB95]

Hello, everyone,

I have a 2D array that consists of a computation of two 1D arrays (Array1, Array2). Now I want to get the row from the 2D array at the position where the maximum value of array 1 is. is that possible? has anyone any idea how to get that? i made a simplified vi to show what i mean

basically i need to split the row of the 2d array, where the value of array 1 its maximum has.

I would be really thankful for any help!!

best regards

Hi,

Just by doing what you are describing :

Find the max of 1D array and get the row value

With that row value extract data from the 2D array

What happens if there are more than one max?

Something like that?

Edit:

LOL I'm late to the party.  But mine doesn't involve transposing.  😄

Please explain your use of the term "split"? Do you want to just get one row? "split" typically means something else!

Some comments on your VI:

• There is no need to use any local variables. It is also bad because you are changing the value of a control so the next time you run the VI, you get a different result. A shift register would be the correct thing.
• There is no need to maximize the diagram and front panel to the screen. At your state of learning you should be able to look at both as well as having the help window open at the same time.
• Unconditionally appending an element to an empty array is the same as autoindexing at the output boundary. No shift register needed. 
• "Insert into array" is NOT the correct tool to append an element to an existing array. Use "built array" instead!
• Not sure why your array is orange if you exclusively dealing with integers.
• Since both 1D arrays have the same size, all you need is exactly one FOR loop.
• If you would build the array inside the (single) FOR loop, you don't need to transpose.

Here's roughly equivalent code with the solution how the get the row containing the max of the first row.
