I have a vi that I am working on that needs to be able to replace a lot of elements and I would like to replace them all with 1 operation. thanks in advance vivi

You have replace array subset function that you can use.

If you want to replace at différent index, you could just expand the icon and more input will be avalaible.

I tried that but the problem is that I need to replace indexes 3-100 in the x direction and 17-210 in the y direction just to give it some numbers

[Benoit]

You dont have the choice to use an For loop or a while loop

Sorry you have to work... Nothing is free.

lol

I you want to replace a "rectangle" inside a 2D array, you can wire a 2D array into the element input of the Replace Array Subset. In that case, the index you wire into the function will specify where you start the replacing.

[vivi]

how do you tell the function where to stop replacing the elements

[Benoit]

It's use exactly the sise of your new array

You can use Replace Array Subset.  Just wire 17 to the row input, 3 to the column input, and a 2D array to the new element/subarray input.  This will replace all of the rows and columns with the new array.  If you meant you just wanted to replace that one row and one column, wire a 1D array to the input and tell it the position to start.
