Creating a subarray using a Index array function

[Ajit]

Hi,

I have an VI that builds an array from a text file.
Now I need to create a sub array which contains the first 81 rows of the first built array by using an Index array function. I know how to do it using a sub array function but can any one help me n doing it with a index array function.

Thanks and cheers,
Ajit

You might want to create an array constant and then use a for loop to index one row at a time and insert it into the array constant.

Hello all,

You can also dynamically create an array by using a for loop. Just pass your main 2D array into a for loop which runs 81 times. You can then use an "index array" function inside the loop and auto-index the output to create your 81-row 2D array.

I modified your VI and attached it. I hope this helps! Let me know if there is anything further I can help with.
